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.
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.
