Anti-Lock Brake System

Auto Systems and Repair

The purpose of an anti-lock brake system (ABS) is to prevent the wheels from locking up or skidding during braking. If the brakes lock up, the vehicle takes longer to stop and the ability to steer the vehicle is greatly diminished. 

The ABS system prevents wheel lock-up by monitoring each wheel with a wheel speed sensor. When the wheel starts to skid, hydraulic pressure to the brake is temporarily reduced to prevent the wheel from skidding.

Key Component — ABS Valve Assembly

The anti-lock brake system (ABS) valve assembly is operated by the ABS control module. The valves open and close as necessary when the ABS is active, providing the correct brake fluid pressure to each wheel to prevent wheel lockup during braking. More >>
