Computerized ABS is designed to keep the wheels from locking as the brakes are applied.
A locked wheel provides very little or no directional control.
Major components of the anti-lock brake system consist of a
Brake control module,
Solenoid valve assembly,
Speed sensor's
Wiring, and the amber ABS brake warning light.
Brake Control Module:
The brake control module is a compute that receives information from the speed sensor and compares it to the speed of other wheels.
When one wheel is approaching lock-up pressure can be vented allowing the wheel nearing lock-up to speed up.
ABS operates using the same hydraulic principal as conventional brakes.
ABS system only operates when wheel lock-up is emanate.
A bussing noise and bakes pedal vibration is normal during ABS operation.
