DESCRIPTION
NOTE:For more information on brake system, see appropriate BRAKE SYSTEM article in the BRAKES Section.

Bendix-4 Anti-Lock Brake System (ABS) is designed to prevent wheel lock-up during heavy braking. This allows operator to maintain steering control while stopping vehicle in shortest distance possible. Major components are master cylinder, vacuum booster, modulator and pump/motor assembly, wheel speed sensors, and Controller Anti-Lock Brake (CAB). See Fig. 7 . ABS also includes 2 warning lights (Red BRAKE and Amber ANTI-LOCK).
ABS has a self-diagnostic system for trouble shooting and system malfunction warning. ABS uses hydraulic power assist for normal power-assisted braking and to provide a source of high-pressure hydraulic fluid during anti-lock braking. Pedal feel is similar to conventional vacuum-boosted brake system. If additional force is applied during anti-lock stop, or if brake pedal is released and re-applied rapidly, driver may notice a very hard pedal feel. This is due to isolation of master cylinder during ABS operation, as wheel brake pressure is fed from modulator assembly.
