Anti-Lock Brake System (Abs)
WARNING: This page is about a different car, the 1994 Mercury Tracer, 1994 Ford Probe, and 1994 Ford Escort. However, it is still accessible from the selected car via links, so may be relevant.
During normal driving and braking operation, ABS performs like a conventional braking system. Each wheel sensor constantly sends an AC signal to control unit. This information is translated to wheel rotation speed. When the control unit determines that wheel lock-up is about to occur, it activates electromagnetic valves, located inside hydraulic actuator assembly, to increase or decrease hydraulic pressure to each wheel. A slight pulsation can be felt through brake pedal.
