Anti-Lock - TEVES Mark 20: Description

The Teves Mark 20 Anti-Lock Brake System (ABS) is designed to prevent wheel lock-up during heavy braking, allowing the driver to maintain steering control while stopping vehicle in shortest distance possible.

ABS uses a diagonal split hydraulic brake system. In the standard brake mode, the master cylinder primary circuit supplies pressure to right front and left rear brakes. Master cylinder secondary circuit supplies pressure to left front and right rear brakes. During an ABS stop, each wheel is independently controlled by using separate hydraulic circuits for each brake. ABS will automatically turn off when vehicle speed is less than 5 MPH.

ABS is equipped with a Red BRAKE warning light and Amber ABS warning light located on instrument cluster. The system is also equipped with Controller Anti-Lock Brake (CAB), Hydraulic Control Unit (HCU), brake booster and master cylinder, low brake fluid switch, ABS system relay and pump motor relay. The red BRAKE warning light will be illuminated if the parking brake is applied or if the fluid level in the brake master cylinder is low. The ABS also uses a brakelight switch, 2 proportioning valves and 4 wheel speed sensors. Neon utilizes an ABS system (light) relay in the ABS warning light circuit. This relay is controlled by the Controller Anti-Lock Brake (CAB).
