Rear Brake Shoe Replacement

Brake Shoe Removal

(1) Raise the vehicle.

(2) Remove the wheel.


CAUTION: DO NOT ATTEMPT TO PRESS THE CALIPER PISTON BACK INTO THE BORE AT THIS TIME. A SPECIAL PROCEDURE AND SERVICE TOOL ARE REQUIRED FOR THIS TASK. REFER TO BRAKE SHOE INSTALLATION PROCEDURE FOR DETAILS.

FIGURE 4:

(3) Unseat the operating lever return spring at the caliper (Fig. 4).

(4) Remove the bolt attaching the operating lever to the drive disc (Fig. 4).

FIGURE 5:

(5) Mark the position of the operating lever before removal (Fig. 5). Use paint or a scriber to mark the caliper drive disc and operating lever.

FIGURE 6:

(6) Remove operating lever with flat blade screwdriver (Fig. 6).

(7) Remove the operating lever and return spring from the parking brake cable. Replace the return spring if it is warped, bent or distorted.

FIGURE 7:

(8) Pull the parking brake cable out of the mounting flange (Fig. 7).

FIGURE 8:

(9) Remove the upper slide pin with an Allen wrench (Fig. 8).

FIGURE 9:

(10) Loosen the lower slide pin and tilt the caliper rearward (Fig. 9). Do not remove the lower slide pin completely at this time.

FIGURE 10:

(11) Remove the brake shoe retaining pin with a pin punch (Fig. 10). Check condition of the sleeves on the pin. Replace the pin if corroded, or the sleeves are worn or damaged.

FIGURE 11:

(12) Remove the lower slide pin completely and lift the caliper off the rotor (Fig. 11).

(13) Remove the anti-rattle spring and the brake pads.

FIGURE 12:

(14) Remove the rotor retaining nuts and remove the rotor (Fig. 12).

FIGURE 13:

(15) Inspect the slide pin bushings and boots (Fig. 13). Replace these components if corroded, worn, or damaged in any way.

(16) Inspect the caliper. Replace the caliper if leakage is evident or if the piston or piston dust boot is damaged.
(17) Secure the caliper to the axle shaft with wire. Do not allow the brake hose to support the caliper weight.

Brake Shoe Installation

CAUTION: THE REAR CALIPER PISTON MUST BE RESEATED (BOTTOMED) TO COMPENSATE FOR THE NEW BRAKE LINING. HOWEVER, BECAUSE THE PARKING BRAKE SELF-ADJUSTER MECHANISM IS ATTACHED TO THE PISTON, A DIFFERENT SEATING METHOD IS REQUIRED. THE ONLY ACCEPTABLE METHOD IS BY ROTATING THE PISTON BACK INTO THE BORE WITH SPANNER TOOL 6366 (FIG. 14). ANY OTHER SEATING METHOD WILL DAMAGE THE SELFADJUSTER MECHANISM.

FIGURE 15:

(1) Reseat (bottom) the caliper piston in the bore as follows:

(a) Temporarily mount the caliper on the axle shaft (Fig. 15). Install and tighten the caliper slide pins just enough to hold the caliper in place.
(b) Assemble a 3/8" drive extension, rachet handle and 7/16" deepwell socket (Fig. 15).

(c) Insert spanner tool 6366 into the deep well socket (Fig. 15).

(d) Insert the spanner tool lugs into the matching holes in the caliper piston face (Fig. 15).

(e) Rotate the piston in a clockwise direction until fully seated (bottomed) in the bore. Then remove the piston rotating tool.
(2) Remove the caliper slide pins and the caliper.

(3) Install the rotor and rotor retaining nuts.

FIGURE 16:

(4) Position the new brake pads in the caliper and install the caliper on the rotor and axle shaft. The brake pads (Fig. 16) are interchangeable.

(5) Install the caliper slide pins. Tighten the small diameter pin to 28 N-m (21 ft.lbs.) torque and the larger diameter pin to 48 N-m (36 ft. lbs.) torque.

FIGURE 17:

(6) Install the anti-rattle spring (Fig. 17). Be sure the spring is positioned so the brake shoe retaining pin will go through the brake pads and the loops at each end of the anti-rattle spring.
(7) Install the brake shoe retaining pin. Be sure the pin goes through both brake pads and the loops of the anti-rattle spring as shown (Fig. 17).

FIGURE 7:

(8) Insert the parking brake cable in the caliper flange (Fig. 7).

(9) Position the return spring on the caliper.

(10) Install the operating lever on the parking brake cable.

(11) Pull the parking brake cable rearward and install the operating lever on the caliper drive disc.

FIGURE 18:

(12) Before installing the return spring, note the return spring ends (Fig. 18). The rounded end goes on the operating lever. The square end goes on the caliper.

FIGURE 19:

(13) Connect the return spring (Fig. 19). Connect the spring to the operating lever first. Then hook the spring onto the caliper with a long screwdriver.
(14) Install the wheel and tire.

(15) Lower the vehicle.

(16) Apply the brakes several times to seat the brake pads and equalize the parking brake adjustment.
