Anti-Lock Brake System: Description

The Bosch Anti-Lock Brake System (ABS) increases vehicle control, directional stability and optimum deceleration in severe braking conditions on most road surfaces. The ABS monitors wheel speed and controls brake line pressure to eliminate uncontrolled skidding.

The ABS consists of an Electronic Brake Control Module (EBCM), modulator valve, lateral accelerometer and wheel speed sensors. See Figure and Figure. The ABS system uses a 3-way hydraulic circuit; one circuit for each front wheel and a common circuit for rear axle.
