The parking brake control system is cable-operated and controlled by an independent hand-operated parking brake control lever. The parking
brake control lever activates the rear brake calipers through a cable and rear caliper lever with a ball in ramp mechanism. The rear caliper
self adjusts to compensate for pad wear through hydraulic operation.
To adjust the cable, operate the parking brake control lever several times.
