The anti - lock brake system operates as follows: - Wheel lock - up is prevented during heavy braking by modulating brake pressure.
- The system permits the driver to maintain steering control and stop the vehicle in the shortest possible distance under most conditions.
- During the anti - lock brake operation, the driver will sense a pulsation in the brake pedal and hear a clicking sound.
- The pedal effort and pedal feel during normal braking are similar to that of a conventional power brake system.
