Disassembly and Assembly

DISASSEMBLY
1. Remove caliper.
2. Open the bleeder screw and drain the brake fluid from the caliper through the brake flex hose fitting. After draining the fluid, close the bleeder screw.

Rear Caliper Assembly:

3. Remove the caliper guide bushing and dust boots.
4. Pry the retaining spring off the dust boot with a screwdriver, then remove piston.
5. Remove and discard the dust boot .
6. Remove the piston seal from the caliper and discard.

CAUTION: Use a plastic or wooden pick to remove seal. A metal tool can scratch or nick the seal groove resulting in a possible seal leak.

7. Remove the parking brake mechanism from the caliper housing.

INSPECTION

NOTE: The caliper bore, piston seal groove and piston must be inspected for cuts, deep scratches and pitting whenever the caliper is rebuilt. The piston and piston bore may be lightly polished with crocus cloth, if deep scratches cannot be removed, the component must be replaced.

- The seal groove in the caliper must be free of deep scratches that would prevent the seal from operating properly.
- Inspect the upper guide pin and lower guide pin bushing for wear.
- Inspect bushing dust boots for damage or poor sealing.

ASSEMBLY

Rear Caliper Assembly:

1. Lubricate the needle bearings with the special grease included in the caliper rebuilding kit.

Fig. 30 Alignment Of The Adjuster Spindle Pins:

2. Install the adjuster spindle in the caliper by aligning the pins of the adjuster spindle with the holes of the caliper.
3. Lubricate a new piston seal with brake fluid and install in caliper groove, then lubricate the caliper bore and caliper piston with brake fluid.
4. Install the dust boot in the caliper bore, then the wire retainer spring.
5. Install the piston in the caliper bore by rotating the piston until seated.
6. Install the upper guide pin dust boot, then the lower guide pin bushing dust boot.
7. Install the caliper upper guide pin, then the lower guide pin bushing.
8. Install the brake pads.
9. Tighten the upper guide pin with allen wrench, then install dust cap with plastic hammer.
10. Install the lower caliper bolt, then torque bolt to 29-36 ft lb.
11. Perform brake bleeding procedures, then pump brake pedal several times to seat the pads.
12. Check fluid level in master cylinder, then spin each rotor to ensure the brakes are not dragging.
13. Install wheel and tire assembly. Torque wheel lug nuts to 65-88 ft lb.
