The parking brake system is a mechanical/electrical system which operates on the rear disc brakes. The system is activated by depressing a foot pedal lever assembly, which sets the rear brake caliper via cables. When the park brake is set and the ignition switch is on, the BRAKE warning lamp on the I/P will illuminate. The park brake is released by shifting the vehicle out of park or activating the manual release.

Important: Use care when performing service operations on or around parking brake cables. Damage to the plastic coating will reduce corrosion protection and if the damaged area passes through the seal, increased parking brake effort could result. Contacting the coating with sharp-edged tools, or with sharp surfaces of the vehicle underbody, should be avoided.
