REMOVAL - REAR DISC BRAKE SHOES1. Raise vehicle.
2. Remove rear wheels and tires from vehicle.
Caliper Assembly Guide Pin Bolts:
3. Remove the 2 guide pin bolts mounting the caliper to the adapter.
Caliper Removal/Installation:
4. Remove caliper from adapter and rotor by first rotating the top of the caliper away from adapter, and then lifting the caliper off the lower machined abutment on adapter.
5. Support caliper from rear strut to prevent weight of caliper from damaging the flexible brake hose.
6. Remove rear rotor from hub/bearing. Then inspect drum-in-hat parking brake shoes and parking brake braking surface on rotor for any signs of excessive wear or damage. Replace parking brake shoes if required.
7. Remove outboard brake pad from caliper by prying brake pad retaining clip over raised area on caliper. Then slide brake pad down and off the caliper.
Removing Installing Inboard Brake Shoe:
8. Pull inboard brake pad away from caliper piston, until retaining clip is free from cavity in 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 7.0 mm (9/32 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 remove from.
INSTALLATION - REAR DISC BRAKE SHOES
1. Completely retract the caliper piston back into the piston bore of the caliper. This is required for caliper installation when new brake pad assemblies are installed on caliper.
2. Lubricate both adapter abutments with a liberal amount of Mopers Multipurpose Lubricant, or equivalent.
3. Install rear rotor on hub making sure it is squarely seated on face of hub.
4. Remove protective paper from noise suppression gasket on both inner and outer brake pad assemblies (if equipped).
5. Install new inboard brake pad into caliper piston by firmly pressing it into bore of piston using thumbs. Be sure inboard brake shoe is positioned squarely against face of piston.
6. Slide new outboard brake pad onto the caliper. Be sure retaining clip is squarely seated in the depressed areas on the caliper.
CAUTION: Use care when installing caliper assembly onto adapter, so the guide pin bushings and sleeves do not get damaged by the mounting bosses on adapter.
7. Carefully lower caliper and brake shoes over rotor reversing the required removal procedure. Make sure that caliper guide pin bolts, bushings and sleeves are clear of the adapter bosses.
CAUTION: Extreme caution should be taken not to cross thread the caliper guide pin bolts when they are installed.
8. Install caliper guide pin bolts into adapter.. Tighten the guide pin bolts to a torque of 22 Nm (192 inch lbs.).
9. Install the wheels and tires.
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. Lower vehicle.
12. Check brake fluid level.
NOTE: Before vehicle is moved after any brake service work, pump the brake pedal several times to insure the vehicle has a firm brake pedal.
13. Road test the vehicle and make several stops to wear off any foreign material on the brakes and to seat the brake pads.
