## FOUR WHEEL ANTI-LOCK BRAKE SYSTEM

### Description and Operation

#### STANZA

The Anti-lock Brake System (ABS) employs a speed sensor at each wheel sending signals to the ECU. The control unit can trigger any or all of 4 solenoids within the hydraulic actuator. This system allows optimal control of the braking effort at each wheel. This model uses a Dual Proportioning Valve (DPV) to further control distribution to the rear wheels. On this model, the primary circuit is the right front and left rear wheels.
