Rear Disc Brakes

The rear disc brakes are similar to front disc brakes, however, there are several distinctive features that require different service procedures. The single piston, floating caliper rear disc brake system includes a hub and bearing assembly, adapter, rotor, caliper, and brake shoes. The parking brake system on vehicles equipped with rear disc brakes, consists of a small duo-servo drum brake mounted to the caliper adapter. The drum brake shoes expand out against a braking surface (hat section) on the inside area of the rotor.

This vehicle is equipped with a caliper having a 42 mm (1.65 inch) piston and uses a 15 inch solid nonvented rotor.

The disc brake caliper floats on rubber bushings using threaded guide pin bolts which are attached to the back side of the adapter.

Rear Disc Brake Components:

The adapter and rotor shield are mounted to the rear axle. The adapter is used to mount the brake shoes and actuating cables for the parking brake system. The adapter is also used to mount the rear caliper. The adapter has two machined abutments which are used to position and align the caliper and brake shoes for movement inboard and outboard.
