Park brake application is completely independent of the hydraulic brake system. The park brake system is a mechanical system which operates the rear disc brakes through the calipers. The system is activated by depressing the park brake pedal, which applies the rear disc brakes via cables. When the park brake is set and the ignition switch is on, the BRAKE warning lamp on the instrument panel will be on. The park brake is released by pushing the pedal down until a click is heard and then releasing. The pedal will click again and the BRAKE lamp in the instrument panel will go out when the park brake system is fully released.
