REMOVAL - REAR DISC BRAKE SHOES1. Raise vehicle on jackstands or centered on a hoist.
2. Remove rear wheel and tire assemblies from vehicle.
3. Remove the 2 caliper assembly to adapter guide pin bolts.
Removing/Installing Caliper Assembly:
4. Remove caliper from adapter using the following procedure. First rotate top of caliper away from adapter. Then lift caliper assembly off bottom abutment of adapter to remove it from the vehicle.
5. Support caliper assembly firmly from rear strut to prevent weight of caliper from damaging the flexible Brake hose
6. Remove the rear rotor from the hub by pulling it straight off the wheel mounting studs.
7. Remove outboard brake shoe, by prying brake shoe retaining clip over raised area on caliper and sliding the shoe off the caliper.
Removing Installing Inboard Brake Shoe:
8. Pull inboard brake shoe away from piston, until the retaining clip is free from the cavity in the piston.
CLEANING - DISC BRAKE SHOES
WARNING: DUST AND DIRT ACCUMULATING ON BRAKE PARTS DURING NORMAL USE MAY CONTAIN ASBESTOS FIBERS FROM PRODUCTION OR AFTERMARKET BRAKE LININGS. BREATHING EXCESSIVE CONCENTRATIONS OF ASBESTOS FIBERS CAN CAUSE SERIOUS BODILY HARM. EXERCISE CARE WHEN SERVICING BRAKE PARTS. DO NOT SAND OR GRIND BRAKE LINING UNLESS EQUIPMENT USED IS DESIGNED TO CONTAIN THE DUST RESIDUE. DO NOT CLEAN BRAKE PARTS WITH COMPRESSED AIR OR BY DRY BRUSHING. CLEANING SHOULD BE DONE BY DAMPENING THE BRAKE COMPONENTS WITH A FINE MIST OF WATER, THEN WIPING THE BRAKE COMPONENTS CLEAN WITH A DAMPENED CLOTH. DISPOSE OF CLOTH AND ALL RESIDUE CONTAINING ASBESTOS FIBERS IN AN IMPERMEABLE CONTAINER WITH THE APPROPRIATE LABEL. FOLLOW PRACTICES PRESCRIBED BY THE OCCUPATIONAL SAFETY AND HEALTH ADMINISTRATION (OSHA) AND THE ENVIRONMENTAL PROTECTION AGENCY (EPA) FOR THE HANDLING, PROCESSING, AND DISPOSING OF DUST OR DEBRIS THAT MAY CONTAIN ASBESTOS FIBERS.
INSPECTION - DISC BRAKE SHOES
Visually inspect brake shoes (pads) for uneven lining wear. Also inspect for excessive lining deterioration. Check the clearance between the tips of the wear indicators on the shoes (if equipped) and the brake rotors.
If a visual inspection does not adequately determine the condition of the lining, a physical check will be necessary. To check the amount of lining wear, remove the disc brake shoes from the calipers.
Measure each brake shoe. The combined brake shoe and its lining material thickness should be measured at its thinnest point.
- For front disc brake shoes, when a set of brake shoes are worn to a thickness of approximately 7.95 mm (5/16 inch), they should be replaced.
- For rear disc brake shoes, when a set of brake shoes are worn to a thickness of approximately 7.0 mm (9/32 inch), they should be replaced.
- Typically, if front shoes are worn out, both fronts and rears need to be replaced. Make sure to check rears.
Replace both disc brake shoes (inboard and outboard) on each caliper. It is necessary to replace the shoes on the opposite side of the vehicle as well as the shoes failing inspection. If the brake shoe assemblies do not require replacement, be sure to reinstall the brake shoes in the original position they were removed from.
INSTALLATION - REAR DISC BRAKE SHOES
NOTE: Step 1 below is only required when installing a caliper after new brake shoes have been installed.
1. Completely retract caliper piston back into piston bore of caliper assembly.
2. Lubricate both adapter abutments with a liberal amount of Mopar Multipurpose Lubricant, or equivalent.
3. Install the rear rotor on the hub, making sure it is squarely seated on the face of the hub.
4. Remove the protective paper from the noise suppression gasket on both the inner and outer brake shoe assemblies (if equipped).
5. Install the new inboard brake shoe assembly into the caliper piston by firmly pressing into piston bore with thumbs. Be sure inboard brake shoe assembly is positioned squarely against the face of the caliper piston.
6. Slide the new outboard brake shoe assembly onto the caliper assembly.
CAUTION: Use care when installing the caliper assembly onto the adapter, so the caliper guide pin bushings do not get damaged by the mounting bosses.
7. Carefully lower caliper and brake shoes over rotor and onto adapter, reversing the removal procedure.
CAUTION: When installing the caliper guide pin bolts extreme caution should be taken not to cross thread the guide pin bolts.
8. Install the caliper guide pin bolts. Tighten the guide pin bolts to a torque of 22 Nm (192 inch lbs.).
9. Install the wheel and tire assembly.
10. Tighten the wheel mounting stud nuts in proper sequence until all nuts are torqued to half specification. Then repeat the tightening sequence to the full specified torque of 135 Nm (100 ft. lbs.).
11. Remove jackstands or lower hoist.
CAUTION: Before moving vehicle, pump the brake pedal several times to insure the vehicle has a firm brake pedal to adequately stop the vehicle.
12. Road test the vehicle and make several stops to wear off any foreign material on the brakes and to seat the brake shoe linings.
