Car Brake System
Car Brake System
Brakes are an incredible invention of science. If we want to stop the car we push the break. Pushing down on the brake pedal slow down a car to a stop. The brake is controlled by a complete system called Car Break System. In all vehicles, break system is simple and typical. The basic system is same but few extra features are added in different models. Find more about car brake system
The car brake system consists of a Master Cylinder, Brake Fluid and Brake Lines that includes Disc Brakes, Drum Brakes, Parking Brakes, Power Brake Booster and Anti-Lock Brakes (ABS).
A typical brake system has disk brakes on the front and/or disk or drum brakes in the rear. These are connected by a system of hoses and tubes that link the brake at each wheel to the master cylinder. Other systems connected are the parking brakes, power brake booster, and the anti-lock system.
A car in motion has a lot of kinetic energy, the energy of motion. The brakes have to get rid of that kinetic energy to stop the car. It is done by using the force of friction to convert that kinetic energy into heat. On a disk brake, the fluid from the master cylinder is forced into a caliper where it presses against a piston. The piston, in turn, squeezes two brake pads against the disk (rotor), which is attached to the wheel, forcing it to slow down or stop.
When you step on the brake pedal, you are actually pushing against a plunger in the master cylinder, which forces hydraulic oil (brake fluid) through a series of tubes and hoses to the braking unit at each wheel. Since hydraulic fluid (or any fluid for that matter) cannot be compressed, pushing fluid through a pipe is just like pushing a steel bar through a pipe.
The break fluid passes through many twists and turns on its way to its destination, arriving with the exact same motion and pressure that it started with. It is very important that the fluid is in pure liquid form and there are no air bubbles in it. Air in the fluid causes sponginess to the pedal and severely reduces braking efficiency.
With drum brakes, fluid is forced into the wheel cylinder, which pushes the brake shoes out so that the friction linings are pressed against the drum, which is attached to the wheel, causing the wheel to stop.
In either case, the friction surfaces of the pads on a disk brake system, or the shoes on a drum brake convert the forward motion of the vehicle into heat. Heat is what causes the friction surfaces (linings) of the pads and shoes to eventually wear out and require replacement.
The modern automotive brake system has been refined for over 100 years and has become extremely dependable and efficient. If a Car Brake System fails then it is very difficult to stop the car. In modern cars, this system is on the automatic mechanism. In the newly introduced Self-driving cars driver do has to worry about the pushing the break as it is done by the automatically programmed system.
