Removal & Installation
- Before servicing the vehicle, refer to the Precautions Section.
- Raise and safely support the vehicle.
Remove wheel and tire assembly.
NOTEWhen removing or installing a caliper guide pin bolt, it is necessary to hold the guide pin stationary while turning the bolt. Hold the guide pin stationary using a wrench placed upon the pin's hex-shaped head.
- Remove the 2 caliper guide pin bolts.
- Remove the disc brake caliper from the disc brake adapter bracket and hang it out of the way using wire or a bungee cord. Use care not to overextend the brake hose or parking brake cable when doing this.
- Remove the brake pads from the caliper adapter bracket.
If necessary, seat (bottom) the caliper piston in the bore as follows:
- Assemble a 3 / 8 inch drive ratchet handle and an extension (3).
- Insert the extension through Special Tool 8807-1 (2).
- Place Special Tool 8807-2 (1) on the end of the extension.
- Insert the lugs on Special Tool 8807-2 into the notches in the face of the caliper piston (5).
- Thread the screw drive on Special Tool 8807-1 down until it contacts the top of Special Tool 8807-2 which is against the caliper piston. Do not over tighten the screw-drive. Damage to the piston can occur.
Turn Special Tool 8807-2 with the ratchet, rotating the piston in a clockwise direction until it is fully seated (bottomed) in the bore. It may be necessary to turn Special Tool 8807-1 with Special Tool 8807-2 to start the process of piston retraction.
Make sure the abutment shims (4) are in place on both the upper and lower slide abutments of the caliper adapter (3).
NOTEIf the brake pads have a protective paper on the rear face of the brake pad plate, it must be removed before pad installation.
Place the brake pads (2, 5) in the abutment shims (3) clipped into the disc brake caliper adapter bracket (3) as shown.
WARNINGUse care when installing the caliper onto the adapter bracket to avoid damaging the guide pin boots.
- Install the disc brake caliper over the brake pads on the brake caliper adapter bracket.
- Align the caliper guide pin bolt holes with the adapter bracket. Install the upper and lower caliper guide pin bolts. Tighten the guide pin bolts to 26 ft. lbs. (35 Nm).
- Install the tire and wheel assembly and tighten the wheel mounting nuts to 100 ft. lbs. (135 Nm).
- Lower the vehicle.
- Pump the brake pedal several times to ensure the vehicle has a firm brake pedal before moving the vehicle.
- Check and adjust the brake fluid level as necessary.
- Road test the vehicle and make several stops to wear off any foreign material on the brakes and to seat the brake pads.
