DESCRIPTION - (EARLY 2500/3500 MODELS WITH REAR DRUM BRAKES)

The parking brakes are operated by a system of cables and levers attached to the rear brake shoes. The rear drum brake shoes serve as the parking brakes. The shoes make contact with the brake drum surface by a cable and lever mechanism attached to the secondary brake shoe.

The front parking brake cable is connected to the parking brake pedal and to an intermediate cable. The intermediate cable connects the front cable to the rear cables.

The parking brake pedal assembly is mounted on the driver side cowl panel. The front cable is directly attached to the assembly. The pedal assembly contains a spring loaded, torsion-type mechanism that will hold the cable in the applied position and allow the pedal to return. A rod used to release the torsion mechanism and return the pedal to normal position.
