The Anti-Lock Brake System (ABS) prevents wheel lock-up by monitoring wheel speed and altering pressure to the wheels. This is accomplished using an anti-lock brake module, power brake hydraulic booster, electric pump, accumulator, three channel modulator and wheel speed sensors.

In the event of emergency braking, monitors will read individual wheel speed so that maximum braking effectiveness can be maintained at all times. As wheel speed...
