ANTI-LOCK BRAKES

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.
The following slides show the common ABS components.
Some components are part of both the conventional and ABS system.
Drivers may experience a pulsation in the brake pedal, or pedal kick back during an ABS stop. This is normal and not to be confused with a conventional brake pedal pulsation
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.
If a wheel is to fast pressure can be increased to slow down the wheel.
If both wheel are approximately the same speed the brake control module can enter a pressure hold mode of operation.
