Parking Brake System: Description and Operation

DESCRIPTION






All vehicles are equipped with a center mounted, hand operated park brake lever. The park brake lever is located in the vehicle, between the driver and passenger seat, and mounted to the console bracket which is welded to the floor pan.
On vehicles equipped with rear drum brakes, the rear wheel service brakes also act as the vehicle's parking brakes.
On vehicles equipped with rear disc brakes, the rear parking brakes have their own set of cable operated brake shoes located behind the rear disc brake rotor. The interior (or hat section) of the rear disc brake rotor acts as the parking brake drum. There is an individual flexible steel parking brake cable for each rear wheel, which are joined using a park cable equalizer before terminating at the floor mounted, hand operated park brake lever.
There is an individual flexible steel parking brake cable for each rear wheel, which are joined using a park cable equalizer before terminating at the floor mounted, hand operated park brake lever.
On this vehicle, the parking brake lever output cable is not replaceable as a separate component of the parking brake lever. Never attempt to repair the parking brake output cable in any manner.

OPERATION
On vehicles equipped with rear drum brakes, the rear drum brake shoes, when acting as parking brakes, are mechanically operated using an internal actuating lever and strut which is connected to a flexible steel cable. There is an individual park brake cable for each rear wheel, which are joined using a park cable equalizer before terminating at the floor mounted, hand operated park brake lever.
On vehicles equipped with rear disc brakes, the rear parking brakes have their own set of cable operated brake shoes that expand outward against the interior (hat section) of the rear disc brake rotor when applied. There is an individual flexible steel parking brake cable for each rear wheel, which are joined using a park cable equalizer before terminating at the floor mounted, hand operated park brake lever.






This vehicle uses a bent nail type park brake cable tension equalizer. The bent nail tension equalizer is to be used only one time to set the park brake cable tension. If the park brake cables require adjustment during the life of the vehicle, a NEW tension equalizer MUST be installed before doing the park cable adjustment procedure.
