Description & Operation

The Anti-Lock Brake System (ABS) prevents wheel lock-up during abrupt braking. The system detects wheel rotation rate and electronically controls fluid pressure applied to brakes.

A slight vibration and noise may be noticed during hard braking. These conditions are normal and indicate anti-lock brake system is functioning properly. If a malfunction occurs in system, anti-lock feature will not function but conventional brakes will continue to operate normally. See Fig 1 through Fig 3 .
