Parking Brake System: Description and Operation

Rear Wheel Parking Brake System with Drum Brakes





Rear Wheel Parking Brake System with Disc Brakes

The parking brake system is cable operated and controlled by an independent hand-operated parking brake control.
The parking brake system operates the rear drum and rear brake disc systems as follows:
- On vehicles with rear drum brakes an independent hand operated parking brake control lever actuates the rear brake shoes directly through a cable system.
- On vehicles with rear disc brakes the parking brake control lever activates the rear brake calipers through a cable and rear brake caliper lever with an integral cam. A pawl within the rear brake caliper rotates the piston adjustment screw to compensate for brake pad wear.
To adjust the cable, operate the parking brake control several times.
