Rear Brake Pad Inspection and Replacement

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 of the inner pad (A) and outer pad (B). Do not include the thickness of the brake pad backing plate.
    Brake pad thickness:
    Standard:
    8.9−9.1 mm (0.35−0.36 in.)
    Service limit:
    1.6 mm (0.06 in.)

  1. If the brake pad thickness is less than the service limit, replace all the pads as a set.

Replacement
  1. Remove the rear wheels.
  1. Remove the flange bolt (A) while holding the pin (B) with a wrench being careful not to damage the pin boot, and pivot the caliper (C) up out of the way. Check the hose and pin boots for damage and deterioration.

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

  1. Remove the pad retainers (A).
  1. Clean the caliper thoroughly; remove any rust, and check for grooves and cracks.
  1. Check the brake disc for damage and cracks.
  1. Clean and install the pad retainers.

  1. Apply Molykote M77 grease to the brake pad side of inner pad shim A, inner pad shim B both sides of outer pad shim (C), the back of pads (D), and the other areas indicated by the arrows. Wipe excess grease off the shims and brake pads. Contaminated brake discs or pads reduce stopping ability. Keep grease off the brake discs and pads.
  1. Install the brake pads and pad shims correctly.Install the brake pads with the wear indicators (E) 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.

  1. Push in the piston (A) so that the caliper will fit over the pads. Make sure the pin boot is in position to prevent damaging it when pivoting the caliper down.
  1. Pivot the caliper (B) down into position. Install the flange bolt (C), and tighten it to the specified torque while holding the pin (D) with a wrench being careful not to damage the pin boot.
  1. Press the brake pedal several times to make sure the brakes work, then test-drive the vehicle.
    NOTE: Engagement of the brake 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. After installation, check for leaks at hose and line joints or connections, and retighten if necessary.
  1. Install the rear wheels.
