Removal & Installation
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.
- Raise the rear of the vehicle, and support it with safety stands in the proper locations.
- Remove the rear wheels.
While holding the caliper pin with a wrench, remove the flange bolt. Be careful not to damage the pin boot. Then pivot the caliper up out of the way. Check the hose and pin boots for damage and deterioration.
Remove the pad shims and brake pads.
Remove the pad retainers from the caliper bracket.
- Clean the caliper bracket thoroughly; remove any rust, and check for grooves and cracks.
- Check the brake disc for damage and cracks.
- Apply a thin coat of M-77 assembly paste (P/N 08798-9010) to the retainers on their mating surfaces (indicated by the arrow) against the caliper bracket.
- Install the pad retainers. Wipe excess assembly paste off the retainers. Keep any assembly paste off the discs and pads.
- Apply a thin coat of M-77 assembly paste (P/N 08798-9010) to the pad side of the shims, the back of the brake pads, and the other areas indicated by the arrows. Wipe excess assembly paste off the pad shims and brake pads. Contaminated brake discs or pads reduce stopping ability. Keep assembly paste off the brake discs and pads.
- Install the brake pads and pad shims correctly. Install the brake pad with the wear indicator on the inside. If you are reusing the brake pads, always reinstall the brake pads in their original positions to prevent a momentary loss of braking efficiency.
- Push in the piston so the caliper will fit over the brake pads. Make sure the piston boot is in position to prevent damaging it when pivoting the caliper down.
Pivot the caliper down into position. Install the flange bolt, and torque it to the specified torque while holding the caliper pin with a wrench. Be careful not to damage the pin boot.
Press the brake pedal several times to make sure the brakes work.
NOTEBrake engagement may require a greater pedal stroke immediately after the brake pads have been replaced. Several applications of the brake pedal will restore the normal pedal stroke.
- After installation, check for leaks at hose and line joints or connections, and retighten if necessary.
