5 - 10 BRAKES - BASE BRAKE SYSTEM
HYDRAULIC/MECHANICAL (Continued)
DESCRIPTION - REAR DISC BRAKES
The rear disc brakes are similar to front disc
brakes, however, there are several distinctive fea-
tures that require different service procedures. This
single piston, floating caliper rear disc brake assem-
bly includes (Fig. 8):
• Disc brake caliper
• Brake shoes (pads/linings)
• Brake rotor
• Disc brake caliper adapter
This vehicle is equipped with a caliper assembly
that has a 36 mm (1.42 in.) piston.
The caliper assembly on all applications floats on
rubber bushings using internal metal sleeves which
are attached to the adapter using threaded guide pin
bolts (Fig. 8).

The adapter and disc shield are mounted to the
rear suspension knuckles of vehicle. The adapter is
used to mount the brake shoes and actuating cables
for the parking brake system. The adapter also
mounts the rear caliper assembly to the vehicle. The
adapter has two machined abutments which are used
to position and align the caliper and brake shoes for
movement inboard and outboard.
This vehicle uses a 14 inch solid non-vented rear
disc brake rotor (Fig. 8). It is a drum-in-hat style. It
serves a dual purpose. The braking disc area of the
rotor functions as a normal brake rotor for disc
brakes. The center section of the rotor has a built-in
brake drum that is used by the parking brakes. Refer
to Parking Brake for more information.
