What are the Functions of the Braking System Components in Car?
Posted: Sep 07, 2020
Brakes are commonly used in a car for converting the kinetic energy into thermal energy for performing the necessary movement of the car. Thus, the braking system allows the driver to slow down or stop it reliably. Whenever you step on the brake pedal, the speed of the spinning wheels underneath the car is reduced correspondingly.
Every car has either a disc braking system or drum braking system for creating the necessary friction to stop the car. On the other hand, many modern cars have a power brake system that uses a brake booster that can amplify the force you have applied on the brake pedal to stop the car. So, you need to apply a little bit of pressure for slowing down the car. Below points define the list of parts of the braking system.
Brake drum and shoes
If your car has a drum brake system, then the brake drum is the alternative option of the brake rotor. When you step on the gas pedal, the drum component of the braking system spins and allow the brake shoes to go inside and push against it. Moreover, the brake shoes are rubbing against the interior of the brake drum because it is alternatives to the brake pad in the disc braking system.
The master cylinder of the brake is used for pushing the hydraulic fluid from the brake fluid reservoir down into the brake lines. For safety reasons, the master cylinders are commonly splitting into two or more individual cylinders. Each cylinder of the master cylinder is easily managing the braking ability of one front wheel and its opposite rear wheel. If anyone of the cylinder is failed, then the other one can slow down the car and help the driver to maintain the control.
Among the several components of the braking system, the brake lines are transferring the brake fluid which is generally defining the hydraulic fluid between the master cylinder and wheels. Unlike the air, the hydraulic fluid is also not compressible means so, whenever you are pushing the brake pedal, the force is directly transferred to the pistons of the brake caliper as well as the shoes in the brake drum.
Brake pedal and booster
In a braking system, the brake pedal is placed next to the gas pedal which is used for slowing down the car whenever you step on it. Moreover, the brake pedal is connected with the entire system inside the braking system. On the other hand, the brake booster is the part of the power braking system that uses a vacuum pump or engine vacuum for amplifying your foot pressure on the brake pedal for slowing down the car.
Brake pad and caliper
Brake pads and the brake calipers are the part of the disc braking system which is rubbing against the spinning back disc for creating the necessary friction. The materials of the brake pads can affect its longevity and optimum heat range. Unlike the brake pads, the brake caliper can clamp the force which is pushing by the brake pads into the brake rotor. The brake caliper is housed with brake lines and pistons for collecting the brake fluid pushes by the master cylinder.
In general, the brake rotors are made up of cast iron which can easily absorb the heat of the brakes. So, in a car, each of its wheels has brake rotors that spin while it moving. For slowing down the brake disc in the braking system, the brake pads and calipers are rubbing against the rotors for creating the necessary friction. As a result, it will slow down the wheels and cars as well. Subsequently, the rear brakes of the car have solid rotors to stop it.
Many of the cars are equipped with an anti-lock braking system that has a wheel speed sensor for determining the spinning speed of each wheel. So, the ABS module is represented as a computer of the braking system for modulating the brakes. Depending on the manufacturing programming, the ABS modules is taking input from the wheel speed sensors for releasing the brake pressure of the specific wheel and allow the tire to regain the traction.
The braking system has numerous components for slowing down the car. All of its components have their own specified working principles and usefulness for making your drive smoother and safer.
