Brake System

Auto Systems and Repair

All drivers know that to stop a vehicle, you press the brake pedal. But how does the pedal make the vehicle stop? Brake systems slow and stop the vehicle by applying pressure to rotating brake discs and/or brake drums, which are attached to each wheel.


Disc Brakes
On vehicles with disc brakes (which is the vast majority), there is a metal disc called a rotor. When the brakes are applied, the brake pads are forced against the brake rotor, which will slow or stop your vehicle.


Drum Brakes
The brake drum fits over the brake shoes. When the brakes are applied, the brake shoes are forced against the inside of the brake drum. This causes the brake drum to stop rotating, which will slow or stop your vehicle. More >>


Related System — Anti-Lock Brakes

The purpose of an anti-lock brake system (ABS) is to prevent the wheels from locking up or skidding during hard braking. If the brakes lock up, the vehicle takes longer to stop and the driver will have a difficult time steering and maintaining control of the vehicle. More >>
