Understanding Purchase Order For Buying Your Car

[ad_1]

Next to the loan contract, the car purchase order is one of the most important documents of the car-buying process. It is your agreement with the dealer on the final cost of the vehicle. Reviewing the items line by line ensures you are in agreement with the bottom line figure, which is what will be the amount you will pay in cash or finance.

Purchase orders for buying your car usually display your personal information on the top and the various dollar amounts that add and subtract to the sales price of the vehicle in a linear format from top to bottom. The top figure is usually the sales price of the car. The following are the most common items you will see added or subtracted:

• Rebates

• Discounts

• Trade allowance

• Guaranteed Assets Protection (GAP)

• Extended Warranty

• Additional protection (ex. Paint, tires, etc)

• All additional equipment or custom parts added to the vehicle

• Dealer fee

• Taxes

• Registration and title fees

• Trade-in payoff

• Down payment

Before getting involved with the details of purchasing or financing the vehicle, review the purchase order and verify no additional products or services were added. Have those items removed and a new car purchase order printed.

This would also be the last chance for you to negotiate a better trade allowance, rebate and discount-give it a shot. You never know. The dealer, registration and title fees are usually not negotiable. The payoff on the trade-in is not either. Again, any changes should result in a new purchase order printed.

Remember, take time to review and fully understand what makes up the bottom-line. Once satisfied with the purchase order, sign it and move on to purchasing or financing the vehicle.

How Much Time Carpet Cleaning Takes

[ad_1]

Are you planning to hire professional help for cleaning or repairing works in your home?

Before hiring the experts, it is better if you ask them in advance that how much time the cleaning procedure will take. This simple question will help you to make plans and understand the basic of the service provided, so that you can relax and get high quality services in quoted time.

While evaluating the time the carpet cleaning process is going to take, the expert floor covering cleaner considers a couple of things:

  • How many rooms are supposed to be cleaned?
  • How dirty are the rooms?
  • Are there stains that need extra attention?
  • Is there any heavy Furniture that had to be moved for cleaning?

The answers of these questions are quite important as these will determine the amount of time it will take to clean the carpet in your home.

The most tedious part of cleaning is the set-up procedure, which begins when the professional cleaner comes to your home and finishes when they begin the cleaning. In this set-up procedure, the cleaner roams around in your home and investigates the floor coverings.

They unload and set-up their hoses and tools, and then machine mounted on their truck is started. Then, they will dry vacuum the area where cleaning takes place. The entire setup process can take 15 to 20 minutes.

After the professional cleaner finishes their set-up, they begin the real cleaning work. The work incorporates the pre-spray step, and the waiting time, any basic spot cleaning, and the washing of the floor covering, lastly the utilisation of carpet protector, and the placement fans for a quicker drying. As it is quite clear, this is a hectic step and requires 20 to 30 minutes per room. This can also vary relying upon the size of the room, and the level of dirt and spots that need be dealt with.

Remember, All Carpets Are Different And Require A Different Cleaning Approach.

Some cleaners are more focused on quantity than others. For a quantity focused cleaner, the most imperative thing is to get in and complete as many cleaning projects as possible in a day. Such cleaners can do the work in half the time estimated and mentioned above. These cleaners assert that they can complete a whole home in 60 minutes. And to achieve this time limit, they often move too fast and fail to deliver desired results.

On the other hand, you need to find a carpet cleaner that offers quality oriented services, instead of quantity oriented. A quality oriented carpet cleaner will pay a greater attention to the details of your carpet and deliver far better results than your expectations.

A Horsepower Calculator For Raising Your Car’s Top Speed

[ad_1]

Horsepower calculators can help you figure out how much horsepower to reach a certain top speed figure with your car. However, before we get into calculating the amount of horsepower you need to reach a certain top speed goal, let us first look into some of the factors affecting your car or vehicle’s top speed.

In general, top speed is physically a balance point between all of the forces acting on your car. When the total sum of the forces propelling the car forward, are exactly equal to the total sum of the forces holding it back, the car can no longer increase its velocity and reaches a steady state top speed.

In doing so, we have broken down the top speed equation into two primary factors which are:

Force: Represented in horsepower

Resistance: Represented in drag

Breaking it down even further:

The factors affecting how much force your car has behind it are related to:

  • The total amount of raw horsepower you have to work with
  • The final drive gearing of your vehicle which combines your transmission gear ratio, your differential final drive ratio, and your wheel and tire package diameter

And the factors affecting how much resistance your car has against it are related to:

  • The car’s aerodynamic profile which is summed up with a single number called the drag coefficient which summarizes different parameters such as:
    • The car’s frontal area (which determines how well the car penetrates through the wall of air ahead of it)
    • The car’s height or ground clearance which determines the portions of the airflow that is split and forced both over the roof line of the car as well as under the belly pan of the vehicle
    • The car’s side profile which determines how the air is expelled after it passes over, under and around the car and determines the characteristics of the low pressure zone behind the rear window or rear bumper of the car. This zone is always effectively ‘sucking’ the car backwards and needs to be minimized.
  • Besides aerodynamic resistance factors, there are also mechanical resistances that come from the high rpm rotation of the engine internals, the transmission, the wheel and tire package, the heavy drive-shaft and axle-shafts (especially on a four wheel drive car for example) and so forth.

Research has shown though (and certain racing classes such as Formula 1 have pragmatically confirmed this) that after the point of about 100 miles per hour that the mechanical resistance factors become less significant in affecting a vehicle’s top speed.

At those speeds, aerodynamic drag is the primary resistive force in deciding a car’s performance which is why in sports like Formula 1, similarly powered vehicles vary significantly in performance based on which car has the proper aerodynamic setting for the best combination of top speed figures as well as aerodynamic assisted traction (down force) during high speed cornering. In comparison, a lower speed racing class such as auto-crossing for example (which is limited by track design to around 80mph for the fastest cars) you find that typically the best performing cars are the ones set up with the best mechanical traction (coming from proper suspension settings and good tire traction) with no real dynamic effects coming from aerodynamic design.

Having said this, gaining an advantage in top speed by altering your car’s drag coefficient can be an expensive process with increasingly diminishing returns. After the first set of basic modifications are exhausted such as…

  • Lowering the car’s ride height to reduce turbulence under the vehicle
  • Installing an aftermarket front bumper with built in air splitter or extending the factory bumper with an add on air splitter to promote more percentage airflow over the car
  • Using lower profile extremities on the car such as lower profile mirrors or rear spoilers with a less aggressive angle (to give a better balance between drag and down force)
  • Paneling the underside of the car to give a smooth lower belly-pan that helps accelerate air under the vehicle and reduce turbulence below. (You will find that manufacturers like Mercedes do this on even their lowest level compact cars to improve high speed stability and highway mileage).
  • Using a kitted or custom made rear bumper with a built in rear diffuser to improve the transition of the two airflow streams from above and below the car merging behind the rear bumper and preventing that low pressure zone behind the bumper from sucking the car backwards.
  • Chopping the top on the car and lowering the roof-line height with respect to the hood and trunk (think of the roof height on a Corvette vs on a Jeep to get a better understanding of why this works)
  • Using strategically placed vents in the hood and front and rear fenders to promote airflow through certain high pressure zones (such as under the hood or in the wheel wells) to reduce the pressure in these zones and help increase the airflow through the vehicle

… once this list of modifications is exhausted, you will find that your coefficient of drag may have realistically dropped by 30%. However top speed relates to drag as follows:

Power to overcome air drag = fA x Cd x 0.00256 x mph cubed / 375

Notice in this equation that the cube of the top speed is related to the coefficient of drag Cd and so altering your drag coefficient from a typical 0.45 to a more sporty 0.30 ( a reduction of 30%) only results in a 12% increase in your actual top speed (i.e. going from a top speed of 100 to 112mph)

Yes this is a notable gain, but to do something as significant as doubling your top speed, you’re going to have eventually start to increase your overall power level. This is a realization that was quickly apparent to Volkswagen designers working on the 1100hp Bugatti Veryron and is precisely the reason they had to use so much power to reach their 400 kph top speed target.

So going back to this equation stated above, we know that if a car is power limited in its top speed run (where we have more gears to use for acceleration or where we reach our top speed in top gear much earlier than red line) then we know that increasing the engine’s horsepower to take advantage of the remaining rpm range (or gear ratios) is a very practical way of raising the car’s top speed.

In a practical sense, even if the coefficient of drag is unknown on the car in question, it is possible to calculate how much power is required to reach a certain top speed goal by comparing your current power and top speed levels, with your target top speed level. By doing so, and by using the equation below (derived from the general equation above) we get:

New horsepower = old horsepower * (new top speed / old top speed)^cubed

A practical example that is close to home for me is the 320 horsepower 3000GT VR4. This twin turbocharged car comes with a great aerodynamic shape and is capable in stock form of reaching a top speed of a 160 miles per in 5th gear at 6000 rpms with 1000 rpms to go in that gear and a whole unused 6th gear.

Having the car so obviously power limited (rather than gear limited or drag limited) in its top speed, some of the enthusiasts have gone on to modify this car and break the 200mph barrier.

Applying our formula above:

New horsepower = 320 hp * ( 200mph / 160mph) ^3

New horsepower = 625 horsepower

So what this says, is that to reach a top speed of 200mph in a 3000GT VR4, we know that we will require at least 625 horsepower (assuming that we have enough gears and rpms to increase our wheel rotational speed by 200/160 or 25% while still operating under the car’s redline rpm).

As a final note, it may seem insane to try and double your car’s horsepower and take to a top speed that is well beyond any speed limit you will ever run into on a normal road however:

1- There certain platforms such as the Chevy Corvette, the Mitsubishi 3000GT, the Toyota Supra…etc where doubling or tripling the power levels on these iconic sports cars is not only common practice, but also relatively cheap ($7000 for the 3000GT using Dynamic Racing’s “Diablo Killer” upgrade package)

2- There are also sanctioned racing classes that allow enthusiasts to race their cars on top speed tests as well as standing mile acceleration tests. These are very addictive and difficult racing classes that attract only the most dedicated of enthusiasts to extract every ounce of aerodynamic design, horsepower, traction, gearing, stability and longevity out of their vehicles and have become more of a racing cult or an addiction that is hard to break.

The Best Design For Your HHO Fuel Cell

[ad_1]

Want to build an HHO fuel cell but not sure what type to choose? While most cells will generate some HHO, there can be an enormous difference in output from one to another – so it’s important to get the design right.

HHO is created by electrolysis: electricity conducted through water between two charged poles, or electrodes. The substance and form of the electrodes can vary, although they must be made of an inert metal, preferably stainless steel. The four basic electrode designs are described below.

The type of electrode that is easiest to build – and one of the most popular – consists of two or more wires wrapped in a spiral around a support mechanism. Unfortunately it is also the least effective, as so little metal (maybe a few square inches) is actually exposed. The the amount of HHO gas that can be generated directly relates to the surface area of the electrodes.

The second kind of electrode is made out of steel mesh, similar to the mesh you would use for screen doors or windows. The mesh is cut to fit into a container and stacked in various configurations. Each layer must be insulated from the others – if the layers contact each other, they can cause a short. This type of electrolyzer makes a lot of bubbles but is not very impressive in terms of the density of HHO gas produced.

Plate designs are the most widely used and the most efficient. Because of their large surface area, plate electrodes have the highest conversion of energy to Hydrogen and Oxygen, while wasting very little energy in the form of heat. High quality stainless steel plates are corrosion resistant, which is why they are used in industry to generate vast quantities of gas.

Tube designs are second in efficiency to metal plates. The tubes may be placed in a ring Stanley Meyer-style or stacked concentrically, one onside another. The problem with tubes is that their maximum usable area is going to be limited by the smallest tube. Tubes, along with spirals, are also prone to overheating.

Those are the four main types of electrodes. There are also two different styles of fuel cells: wet and dry. In a wet cell, the plate stack (or other type of electrode) is completely immersed in electrolyte solution. In a dry cell, the stack is not immersed. Instead, the solution is housed in an external reservoir and gravity fed through holes that have been drilled into the plates.

Both styles of cell have good and bad design points. Recently a third style of cell been developed that seems to combine the best aspects of wet and dry cells. Generally speaking, in this hybrid type the cell container serves as the reservoir but the electrolyte remains below the top of the plates.

As you can see there is no definitive version of an HHO fuel cell, which means it can be difficult knowing exactly which type to build. Using plans that have been developed by experts and tested over and over again can certainly save a lot of time. The most important thing is to just get started, and reap the amazing benefits than an HHO cell can provide.

Automatic Or Manual Van?

[ad_1]

There are many things to consider when you are purchasing a van. First, is it large enough for the needs of your company? Will it haul everything? If not, you might need to invest in a larger van. But that is an obvious decision – right! There are other factors about choosing the van that are not as obvious. These decisions include items such as whether or not you should purchase an automatic transmission or manual transmission van. There are pros and cons to each type of van. Here is a list of some of the ups and downs of both to help you decide which option is better for you.

Automatic Transmission

First of all, automatic transmission is known to be the more enjoyable way to drive around town. However, is that what you care about? Are you the one that is going to be driving the vehicle? Or, are you going to be delegating that task to other members of your staff. If so, then the decision to go with automatic transmission might change. However, if your driver is not as skilled, many people consider automatic transmission to be safer than manual. It does actually reduce driving effort by 25 percent. Therefore, it may be a better option for you and those that work for your company. However, the main drawback to automatic transmission is the gas mileage. Since the transmission is done on a standard level, the gas mileage is not as good. Therefore, if you are looking to save money on fuel, it may not be the way to go.

Manual Transmission

You also have the option of purchasing a manual transmission van for your company. While manual transmission cars are less popular today, they are still in use. And they allow the driver to have more control and operation of the car and it’s speed. Some may argue that they can cause a driver to become worse given the focus that is required. However, others will say that this focus is great in a day of distractions. Automatic transmission easily enables drivers to become distracted with cellphones, texting, the radio, etc. These items could cause injury on the road. Furthermore, a manual transmission van will save you money. It is less expensive to purchase initially and less expensive to fuel when you are driving it. For many, it is a more economical choice.

Test drive both today and see what you think!

A Story for the Australian Automotive Industry

[ad_1]

Introduction to the Topic

Australia is one of only a few countries with the capabilities to design cars from scratch and manufacture in significant volumes. Car sales in Australia are also an important factor of the Australian Automotive Industry and the Australian Economy in total.

The Australian Auto Industry (A.A.I. in short) can be divided into two interrelated sectors, the Production ( Manufacturing) sector and the Car Sales (or Import-Sales) sector, both equally important for the total performance of the A.A.I. On one hand, the Manufacturing sector refers to the market conditions under which Australian Manufacturing businesses compete, by producing vehicles and related products, with the main aim of maximizing profits. On the other hand, the Sales sector refers to the market conditions under which car representative sale businesses compete, by the sale of cars and related products, having the same aim with businesses within sector one.

It is very important to state the distinction between these two sectors within the A.A.I., as we will be talking about two different market structures, business strategies, competition conditions, e.t.c. In order to analyse these market structures it would be appropriate to develop two economic models, one for each A.A.I. sector.

1.1-Analyzing the Manufacturing Sector

There is only one market structure that can best describe the market conditions in the Manufacturing sector if A.A.I., this is Oligopoly. As there are only two organizations that produce cars in Australia, and these are Ford and Holden, the competition methods and pricing strategies are based between these two organizations. The following economic model shall help define the competition and economic conditions for the Australian Automotive Manufacturing market.

The first important characteristic of Oligopoly that needs to be stated is that prices between competitors tend to be “sticky”, which means that they change less frequently than any other market structure. This statement will be explained in more detail later on, when we will be developing the Game-Theory model, as it is a very important concept of competition. The second most important characteristic is that when prices do change, firms are likely to change their pricing policies together. These two characteristics can boost up competition within the market. Firms will either try to match rivals’ price changes or ignore them. This is depended on the Game-Theory that is explained bellow.

However, the recent market conditions for the Australian Automotive Industry and the actions of the Australian Government have worsen the competition conditions and possible pricing options available for firms in the market. The production and maintenance costs for a manufacturing business in Australia are already high and rising, mostly due to lack of economic resources and advance of technology. That is, as Holden and Ford try to compete each other, given that prices tend to be “sticky”, they are forced to focus on technological advantage and marketing. Both of these business sectors produce high costs. Furthermore, the Australian government has made it clear that is unwilling to further subsidize automotive organizations in the market. All these factors stated above produce a negative effect on the competitiveness of both firms. In other words, rising costs alongside with decreased revenue push firms in experiencing lower and decreasing levels of profitability.

Profitability and the level of competitiveness are highly interrelated in an oligopolistic market structure, being the two most important factors, alongside with product differentiation, in the competition policies that the firms follow. When we say that the level of competitiveness of a firm is very low, we mean that the firm cannot react effectively to any price changes or competition changes or even changes in production costs. This may leave the firm depended on its’ competitor’s pricing and competition actions, not being able to affect the market competitiveness at all. The firm is then exposed to external danger and can be pushed out of the market, or even worse to shut production and declare bankrupt.

1.2- The Game-Theory Model for Oligopoly

The Game Theory model is used to explain the pricing and competition policies of firms in an oligopolistic market structure. Furthermore, it can show the few different competition policies based on pricing that the two firms can follow, that is High and Low as stated above. All firms in this market structure follow a Game-Theory model, although it is surely more detailed than our example, in the process of trying to forecast competitors’ pricing and competition movements and also keep track of the competition levels in the market and market share. But how does this happen?

For example, let’s say that there are four different fields, each divided in half. These fields represent the pricing strategies that Holden and Ford may use in the process of competing each other. Field A and C represent a High-Pricing policy for Holden, while fields A and B represent a High-Pricing policy for Ford. Lastly, fields B and D represent a Low-Pricing policy for Holden, while fields C and D represent a Low-Pricing policy for Ford. When both firms decide to follow a High-Pricing policy they share a profit of, let’s say, $12 million. If Holden decided to move to a Low-Pricing policy it will experience a maximum of $15 million profit, while Ford’s profitability will fall to $6 million. The exact opposite may also occur, while if both firms decided to follow a Low-Pricing policy they would realize a maximum of $8 million of profit.

What we can identify from the above example is that firms in an oligopolistic competitive market rarely change their pricing policies because this may produce a negative effect on their profitability levels. However, Holden and Ford, being the only two firms in the Australian Automotive Industry, they will focus on competing through product differentiation and marketing. That is, they will try to compete by differentiating their products, for example by producing vehicles with different features, or even base their production on technological advantage. Marketing plays an important role here, as it is the main tool that delivers and connects the customer with product. For example, if Holden introduces a new driving technology that improves driving experience and safety and produces this technology alongside with a newly designed vehicle, it is quite likely that Holden will effectively differentiate its newly designed vehicle from a relative vehicle of Ford and lure more customers in the store. Holden may also use marketing techniques to deliver this technology to the public, in the form of knowledge; hence try to boost sales without changing its pricing policy. However, it is important to state that this new technology may produce higher production costs, if not evaluated properly; hence Holden can only rely in increasing its market share to gain greater profitability. The sales part, however, will be analyzed in more extend within the next chapter of this report.

The Game-Theory is not just a theory for the Automotive Industry in Australia, it’s a fact. It shows us that auto manufacturers in Australia have based their competition strategies on all the factors stated above and as much as they possibly can on pricing strategies. They may advertise that they have low prices, but in fact their prices are very stable. If we have a close look at Holden’s or Ford’s websites, we will identify that there is a huge variety of products and each firm competes in that. However, the new market conditions stated before have greatly changed the way auto manufacturers think of the future and this in turn may change their pricing and competition policies, or even determine their existence in the market.

2.1- Analyzing the Import/Sales Sector

While the auto manufacturers are considered to be operating in an oligopolistic market structure, importing and selling vehicles or relative products is a different story. The import and sale of vehicles is the second and equally important business sector of the Australian Automotive Industry. There are many different car selling businesses and we shall only consider first-hand sales, as second-hand sales in general are not included in economics and more specifically in GDP measurements. To enter the industry hard at all as there are not many barriers to entry, however someone who is interested needs to consider of the high costs in setting up an automotive dealership. All businesses in this market are mostly based on product differentiation to compete and while prices are not “sticky”, pricing competition is set up by the market mechanism and tends not to be considered a regular phenomenon. Lastly, cost analysis and cost management play a very important role. All of the above characteristics refer to the Monopolistic Competition Market Structure. In this market structure we will focus on two phases, the short-run phase and the long-run phase, each with different competition characteristics and outcomes.

An important factor that we need to state here is that when the costs of developing a vehicle in the manufacturing sector rise, then the cost for selling the vehicle for a dealership may rise as well. This is always depended of course on if the vehicle was produced in Australia and if it was produced overseas, under what economic conditions was it produced. Price might be “sticky” for manufacturers, however prices will change much easier in this sector if needs be. Here firms will change their pricing policies if costs either rise or fall and this is always depended on the market mechanism. The amount of competitiveness along with the amount of price elasticity of demand will depend on how many rivals the monopolistic competitive firm will have to face.

In such market the following situation is very common, a situation that helps us distinct between short-run and long-run:

Stage One

In this stage the firm experiences economic profits. However, this fact will draw new firms in the market causing the profits to be competed away.

Stage Two

The economic losses indicated in this stage will cause many firms to exit the market, as they cannot keep selling under these market conditions.

Stage Three

In the final stage, the market clears-up, or reaches equilibrium point. As all firms that needed to exit the market have done so, the market mechanism comes to the point where no economic profits/losses are realized by the firms. This is the point where the market is most stable.

Studying the situation above we can identify one very important fact for any monopolistic competitive firm in the Australian Automotive Industry/ Sales sector. That is that in this market structure, in the long run, firms will realize only normal profits and the market mechanism will eventually reach an equilibrium point. Hence, in the long-run firms will compete mostly through product differentiation. However, in the short run firms may experience economic profits or losses and this is what causes firms to enter or exit the market and “shows” firms how to compete and when to apply pricing competition policies.

Conclusion

The Australian Automotive Industry may be experiencing rough market conditions, mostly because there is no more government support; however competition and profit maximization is still possible. Thinking of moving overseas is not always a good option for the manufacturing businesses, as the Australian Economy needs the manufacturing sector, as it represents a reasonably big part of GDP.

Market competition conditions are well defined for every manufacturer or car dealership, hence any business in the market ought to use the available to them competition strategies and achieve higher market share and profitability level or stabilize its profitability levels. Either way, these are the main goals for almost every profit-motivated business in any market type under any market structure. However, every business ought to define the market structure that is operating in, so that it can then clearly define its goals, strategies and policies. The market mechanism is in all cases responsible for all the above strategies and most of the cases responsible for setting up pricing policies or indicating pricing and marketing strategies.

The Benefits of a Hand Car Wash

[ad_1]

Our cars are more than just a way for us to get from point A to point B. They are an essential part of our lives. Our cars reflect our personalities and interests. We choose our gasoline based on which brand will help extend the life of the engine. We buy seat covers to protect the upholstery, and sun shades to protect the dashboard. Some people even name their cars. But despite the obvious attachment we have to our vehicles, all too often people neglect the important task of keeping their cars clean.

You might be one of the many people who are in the habit of washing your car at home. Think twice before hauling out the sponge and bucket again. Hand washing, done improperly, can damage your car’s exterior. The grit and dirt clinging to the paint can easily cause scratches. The wrong sort of sponge or soap can also cause damage, or dull the color. Over time, the grime that builds up can even cause corrosion. While this may seem like merely an aesthetic problem, a car with a lackluster exterior will have a depreciated resale value later on. Given how much expense you’ve put into keeping your car running smoothly, doesn’t it make sense to further protect your investment?

Getting your car washed professionally isn’t just good for your car – it’s good for the environment, too. On average, a professional car wash uses about half as much water as it takes to wash your car at home. That means a lower water bill for you, and a lower impact on the planet.

So why choose a hand wash over an automatic wash? The benefit lies in the attention to detail. Nothing gets things cleaner than a person working on a car with their own two hands. Additionally, some of the circular brushes and scrubbers used by automatic washes can be abrasive over time. A good hand wash is gentle enough to protect your paint, and ensures that from headlights to bumper, your car comes back to sparkling.

A Car Brake Repair Primer

[ad_1]

The security of your car is vital, whether it is a Mercedes or a Mazda – even the safest vehicle on earth can have brake failure. If your car’s brakes don’t work properly, the consequences could be fatal. Thus, the brakes are probably the most important part of your vehicle. Car brake repair knowledge is always good to have because you never know if or when your car’s brake system will let you down. If this happens while you’re driving let’s say in the desert, miles away from the nearest garage, you should be able to

  • Perform a brake inspection and troubleshoot the problem
  • Know what it takes to do a car brakes repair
  • If possible, do the fix yourself
  • If not, be able to describe the problem to someone who is able to repair your automobile brakes.

To become able to perform the work listed above, the first thing you need to know is how a car’s brake system works.

A drum system is utilizing hydraulic pressure to press a pad against a brake drum to slow down the speed of the vehicle. Here is how it works:

  • press the brake pedal
  • the piston in the master cylinder sends pressure via the brake lines held by the brake shoe to the wheel cylinders inside the brake drum
  • the friction caused by the shoe pressed against the drum is stopping the wheel from turning

A brake drum is a flat-topped and heavy cylinder, that you normally find somewhere between the wheel rim and the drive wheel. When you press the brake pedal, the friction material held by the brake shoes is pressed against the brake drum. This will slow the rotation of the wheels. A wheel cylinder contains pistons utilizing hydraulic power from the master cylinder to force the brake pads against the brake drum.

Another brake system, called disk brake system is using hydraulic pressure to press a pad against the rotor. This way it slows down the vehicle. Here is how it works:

  • press the brake pedal
  • the piston in the master cylinder is activated and sends pressure via the brake lines to the calliper
  • when the pad makes contact with the rotor, friction is created and this stops the wheel from turning

A rotor is nothing but a circular plate that is gripped by the brake pads for slowing down the vehicle. A brake pad is a pad made of friction material. When pressed against the rotor it stops the wheel from turning. This pad is held by the calliper, which straddles the rotor by using hydraulic pressure from the brake lines. With help from internal pistons it forces the brake pads against the rotors.

Performing this process, the breaking system needs brake fluid. The master cylinder provides this by distributing the brake fluid under pressure, to the entire breaking system of your vehicle.

The description above gives you the knowledge of how two different car brake systems work. These are the first things you need to know when troubleshooting and fixing any problems regarding your vehicle’s brakes. Brake problems can occur in a Cadillac, a VW or even in the safest vehicle brand. There are plenty free resources online which give you step by step instructions on fixing any brake problems that your vehicle may incur. I recommend that you go online and do a search for ‘car auto brake repair’. You’ll be amazed of the list of brake fix resources that will appear within seconds.

Container Transportation: The Pros and the Cons

[ad_1]

Intermodal freight transport is the transportation of freight in intermodal cargo containers, using multiple modes of container transportation, including truck, rail, barge and ship. In this method of transport the actual freight itself is not handled as it is transferred from one transportation mode to another, but rather entire cargo containers and their contents are transferred from truck to rail, or from truck to barge/ship, or from rail to barge/ship, or from barge/ship to truck, etc.

Some of the advantages of intermodal freight transport include:

• Little or No Damage – When cargo is properly packed and sealed in a container, damage should not occur to the container’s contents during transit.

• Labor Savings – The actual cargo is only handled at its point of origin when it is packed into the container and at its final destination when it is unpacked.

• Handling During Shipping Is Eliminated – Once the container is packed and sealed, that container won’t be opened again until it reaches its final destination.

• Flexibility Regarding Types of Transportation – Containers can be transferred from ships to overland transport (trucks and trains) or even to barges for river transport. Barges are used to transport containerized cargo on major river systems like the Mississippi River in the United States and the Rhein River in Germany.

• Specialized Containers – There are a wide range of containers designed to transport different types of cargo, including liquids, frozen goods, compressed or liquefied gases, fast freight and even mini containers for smaller loads of cargo. There are also special containers for transporting livestock, tilting containers which make unloading grain easier and faster, fan-tainers that can ventilate the cargo within with built-in blowers or fans, hang-tainers with hanging systems for garments, and even open-end containers designed to transport long items.

• Little or No Theft/Pilferage – The likelihood of theft or pilferage is greatly reduced or even eliminated when cargo is shipped in sealed containers.

• Time Savings and Improved Efficiency – The use of containers means ships or barges are loaded and unloaded faster which means less time in port and improved efficiency. Cranes can move containers rapidly from ship/barge to trucks or trains for delivery directly to inland destinations.

Some disadvantages of intermodal freight transport include:

• Not Suitable for Transporting Smaller Shipments – Containerization is often not practical for shipping smaller loads because the shipping costs are often too expensive for half container loads.

• Heavy Loads Can Cause Road Damage – Trucks hauling heavy containerized loads can cause additional wear and tear to road surfaces which increase maintenance costs. In the case of public roads and highways, these increased maintenance costs can result in higher taxes to individuals and businesses.

• Delays in Deliveries – As has been experienced in Europe and elsewhere at various times, labor disputes or strikes involving dock workers at harbors or involving rail or trucking workers can delay deliveries.

• Costs at Harbor – Dock dues can be expensive, especially when ships are forced to remain in port for extended periods, as can happen when cargo can’t be unloaded during labor disputes/strikes involving dock workers. In addition, the largest container ships used today require specialized deep-water terminals and handling facilities.

3 Reasons to Buy a Repossessed Car From a Credit Union

[ad_1]

Are you shopping for a deal on a vehicle? Have you ever considered purchasing a repossessed vehicle but didn’t want to pay to locate repos? This article will provide you with information on understanding what a “repo” is, the benefits of buying one directly from the financial institution, and where you as a consumer can locate repossessed repossessed vehicles locally.

1- Value:

Much has been said about buying repossessed vehicles. While most of it has focused on the great deals you get, it’s important to understand what a “repo” is, and why you get a better deal. Calling a car a “repo” doesn’t automatically make it a good deal. A lot of the used cars you see at dealerships were once repos too. Most of the larger Banks will send their repos to “Dealer Only” auctions. Here Dealers will buy them at wholesale, clean them up, and then sell them to consumers for a commission. Once a Dealer adds a commission or fees to the wholesale price, it is now a retail price and the term “repo” is inaccurate. Dealers may still call them “repos”, but in reality this is nothing more than a sales gimmick.

Many of the smaller Credit Unions deal only in lower volumes, and get better results from selling their repos to the public. Typically they will post a link on their website that provides information about their current inventory. By skipping the Dealer and buying directly from your local Credit Unions you avoid paying and fees or commissions for a bona-fide “repo”. Credit Unions are anxious to sell these vehicles and can make added concessions that a Dealer or other private party could not.

2- Trust:

There seems to be a stigma with the term “Used Car Salesman”. Although most Dealers are honest, consumers become somewhat guarded when negotiating a vehicle purchase. Nobody wants to get buyers remorse after they find out they were mislead.

When you buy a repossessed car directly, you can be assured that they are not paying a sales commission or any hidden fees. Credit Unions want nothing more that to retain your trust. The Credit Union motto is; “not for profit, not for charity, but for service”. The Credit Unions have no incentive to sell you on a vehicle you don’t want.

3- Financing:

Credit Unions are not Car Dealers, but they can still sell cars and provide onsite financing. Perhaps the best perk of buying from a Credit Union is the financing. Ask any Car Dealer about financing and they will most likely tell you the Credit Unions are the best. Credit Unions can do things that larger Banks can’t.

Many Credit Unions who sell “repos” will even provide special financing terms as low as 0% financing. When buying these vehicles you can negotiate both the price and the financing terms. If the they can’t budge on the price, try asking for a reduction in the interest rate.

The next step is to start looking for a repo deal. RepoFinder’s website was designed and built with deal-seekers in mind. The website is 100% free to use and is the best place to start your repo search. RepoFinder connects you directly to the Lenders.
