Frequent inhalation of brake pad dust, regardless of material composition, could be hazardous to your health.
  • Avoid breathing dust particles.
  • Never use an air hose or brush to clean brake assemblies. Use an appropriate vacuum cleaner.

Inspection
  1. Remove the rear wheels.
  1. Check the thickness (A) of the inner pad (B) and outer pad (C). Do not include the thickness of the backing plate.
    Brake pad thickness:
    Standard:
    6.8−7.5 mm (0.27−0.30 in.)
    Service limit:
    1.6 mm (0.06 in.)

  1. If the brake pad thickness of any of the pads is less than the service limit, replace the rear brake pads as a set.
  1. Clean the mating surfaces of the brake disc and the inside of the wheel, then install the rear wheels.

Replacement
  1. Remove some brake fluid from the master cylinder.
  1. Remove the rear wheels.
  1. Remove the parking brake cable mounting nut (A).
  1. Remove the flange bolts (B) while holding respective caliper pins (C) with a wrench. Be careful not to damage the pin boot, and remove the caliper (D). Check the hose, the pin boots, and the parking brake cable boots for damage and deterioration.
    NOTE: Do not twist the brake hose and the parking brake cable to prevent damage.

  1. Remove the pad shims (A) and the brake pads (B).

  1. Remove the pad retainers (A).
  1. Clean the caliper bracket (B) thoroughly; remove any rust, and check for grooves and cracks.
    Verify that the caliper pins (C) move in and out smoothly. Clean and lube if needed.
  1. Apply Molykote M77 grease to the retainers on their mating surfaces (indicated by the arrows) against the caliper bracket.
  1. Install the pad retainers. Wipe excess grease off the retainers. Keep the grease off the brake disc and the brake pads.

  1. Rotate the caliper piston (A) clockwise into the cylinder by using the locknut wrench.
    NOTE: Be careful when moving the piston back in the caliper; brake fluid might overflow from the master cylinder's reservoir.

  1. Apply Molykote M77 grease to the pad side of the shims (A), the back of the brake pads (B), and the other areas indicated by the arrows. Wipe excess grease off the pad shims and the brake pads. Keep grease off the brake discs and the brake pads. Contaminated brake discs or brake pads reduce stopping ability.
  1. Install the brake pads and pad shims correctly. Install the brake pad with the wear indicator (C) on the bottom 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.

  1. Align the cutout (A) in the piston (B) with the tab (C) on the inner pad. Lubricate the boot with rubber grease to avoid twisting the piston boot. If the piston boot is twisted, back it out so it is positioned properly.
  1. Install the caliper. Install the flange bolts (D), and tighten it to the specified torque while holding the respective caliper pins (E) with a wrench, being careful not to damage the pin boots and parking brake cable boots.
  1. Install the parking brake cable mounting nut (F).
  1. Clean the mating surfaces of the brake disc and the inside of the wheel, then install the rear wheels.
  1. Press the brake pedal several times to make sure the brakes work.
    NOTE: Engagement may require a greater pedal stroke immediately after the brake pads have been replaced as a set. Several applications of the brake pedal will restore the normal pedal stroke.
  1. Add brake fluid as needed.
  1. After installation, check for leaks at hose and line joints or connections, and retighten if necessary. Test-drive the vehicle, then recheck for leaks.
