The brake system and how it works

Last article we talked about the Anti Locking Braking System or the ABS which is of course useful for the first time drivers and professional drivers’ alike. This helps the vehicle from locking during braking. What we are going to know today is about the brake system and how does it work. For us to know our vehicles better, we should also know some of the basic parts of a vehicle in order for us to use it efficiently and safely. The brakes are a very important part of a vehicle whether it be an old or a new car, it is totally indispensable. This is of course to be able to stop your vehicle whenever you wanted to. And of course, as we all know, when we push down the brakes, it slows the vehicle until it stops.

So to describe it more clearly, the brake system is rather very simple. Using your foot, place it on the brake pedal and apply pressure thus, applying pressure and transmit force from your foot to its brakes through a fluid or a brake fluid that is. However, as the brakes actually require a much greater force than what you can apply with your leg. With this situations, the vehicles have different and methods in multiplying the force of your foot through; mechanical advantage and hydraulic force multiplication.Friction has an important role regarding brakes. The brakes will transmit the force of the tires by using the friction and then the tires also transmit the force to the road using friction. So basically, that is the common principle of how a brake works in your vehicle.

Did you know that there are different kinds of brakes? Each vehicle is designed to a certain kind of brakes. Of course it has the same principle but it also has different kinds on how iit works in different vehicles. These types of brakes are disc brakes, drum brakes, hydraulic breaks, and regenerative brakes that are used in hybrid vehicles.

For the disc brakes, this is for the slowing or even stopping the rotation of a wheel. A brake disc or what is commonly known as a rotor is made up of cast iron or ceramic and it is basically connected to the wheel or the axle. In order for the wheel to stop turning, a friction material in a form of a brake pad is forced mechanically or hydraulically against both sides of the disc. The friction will cause the attached wheel to slow down or even stop the vehicle from moving.

The drum brakes on the other hand produces friction caused by a set of shoes or pads that will press against the inner surface of a rotating drum. The drum I by the way connected to a rotating wheel. The hydraulic brakes however is an arrangement of braking system which uses hydraulic fluid, normally some type of light viscosity petroleum oil that will in turn transfer pressure from the controlling unit. A regenerative brake is an a system or device which allows a vehicle to store part of the kinetic energy that would be lost to heat when braking.At Easy Sports Car Hire, whichever brake system is used in our cars, we are sure that the brake system is in perfect condition because we cautiously and critically double check the vehicles performance and it parts.

Drivers should always be cautious whenever they drive especially on the highway or in heavy traffic. The cars should also be in good condition and there are no damages that can harm the driver and the passengers. Novice drivers or first time drivers are very careful and sometimes nervous on what to do especially when they haven’t experience some troubles happening in their car. Most of the novice drivers will most likely panic whenever they don’t know what to do if ever something unusual happens to their car. The worst thing that could happen to them is to lose their brakes or to stop in the middle of the traffic.

Car companies had made their car very sensitive and user friendly so that novice and as well as professional drivers would be safe in anything that will happen to the car and the passengers. Thus, many cars now have integrated some advanced technology like the GPS and the so called ABS or the Anti Lock Braking System. The ABS is a system on most vehicles wherein it prevents the wheels from locking while you are braking. Why do we need this you ask? This keeps your vehicle safe and secure which has two advantages that will surely give a big help to the drivers. First thing that the ABS can do is to maintain steering control under heavy braking and in most situations, it shortems the braking distance.
So what is really the big difference between the vehicles with ABS and the normal vehicles? If you have a vehicle that has no Anti Locking Brake System, you can manually pump the brakes to prevent the wheels from locking up. So in vehicles with anti locking brake system, the driver’s foot needs to remain firmly on the brake pedal which will allow the system to automatically pump the brakes. This is very helpful especially the inexperienced driver so that the brakes won’t lock up whenever they are braking.

So how does this anti locking braking system work? Basically, the ABS is composed of a central electronic unit which has four speed sensors. These sensors are assigned for each wheel. The ABS also has a two or more hydraulic valves on the brake circuit. These elements are very important to make the ABS more effective and efficient. What it will basically do is to that when it sensed any number of wheels that are rotating slower than the others, which will bring it to lock, it will move the valves to decrease the pressure on the braking circuit. With this process, the vehicle will in turn reduce the braking force on that wheel and it will cause a pulsing feeling through the brake pedal.

Maintaining the safety of our customers is our priority that is why we have cars that has these technologies in order for you to drive safely and have a peace of mind. Our sports car hire vehicles like the Porsche has an ABS that will surely make you happy. Here at Easy Sports Car Hire, we give you the best cars with the best technology which will help you in your driving needs.
