REMOVAL & INSTALLATION
See Figures 1, 2, 3, 4, 5, 6, 7 and 8
- Remove some (one-third to one-half) of the brake fluid from the reservoir. As the caliper piston is pushed back into the caliper, brake fluid will be pushed back through the lines, back into the master cylinder and fluid reservoir, possibly causing the reservoir to overflow.
- Loosen the rear wheel lug nuts.
- Raise the vehicle and support safely. Remove the rear wheels.
- Remove the caliper guide pin bolts.
- Before removing the caliper, use a large C-clamp to press the piston back into the caliper. This will prevent possible damage to the caliper piston.
- Remove the caliper adapter by rotating the unit away from the adapter. Lift the calliper off the bottom abutment of the adapter to remove it from the vehicle.
- Remove the caliper assembly by swinging the top part of the caliper away from the brake rotor edge, then lift the caliper assembly up.
- If the caliper is not being removed for replacement or overhaul, hang the caliper with a strong piece of wire from the rear strut to prevent damage to the brake hose.
- If necessary, remove the rotor from the hub by pulling it straight off the mounting studs.
- Remove the outboard brake pad by prying the brake pad retaining clip over raised area on the caliper. Then slide the pad down and off the caliper.
- Remove the inboard brake pad by pulling away from piston until the retainer clip is free from the cavity in the piston.
- Completely retract the caliper piston back into the piston bore.
- Lubricate both the caliper mating surface and the machined abutment surfaces with multi-purpose lubricant.
- Install the rotor assembly on the hub making sure that it is squarely seated on the face of the hub.
If equipped, remove the protective paper from the noise suppression gasket on both the inner and outer pads.
- Before brake pad installation, be sure to lightly coat the outer backing plate surface of the new brake pads with a disc brake pad anti-squeal lubricant.
- Install brake pads into the caliper assembly making sure both pads are seated securely onto the caliper.
- Install the caliper assembly back into position over the brake rotor and install the caliper guide pin bolts. Tighten the caliper guide pin bolts to 17 ft. lbs. (22 Nm).
- Install the wheels and hand-tighten the lug nuts.
- Lower the vehicle and tighten the lug nuts in a star pattern sequence, to 95 ft. lbs. (129 Nm). Top off the master cylinder to the appropriate level, using DOT 3 type brake fluid only.
- Before moving the vehicle, pump the brakes until a firm pedal is obtained. Road test the vehicle to make sure the brake operation is normal.
Measure lining wear by measuring the combined thickness of the pad and the lining at its thinnest point. The brake lining thickness should be not less than 9 / 32 inch (7mm). If the brake pads are worn below specification, or is excessively worn uneven, replace the rear brake pads. Keep in mind state inspection laws may differ from these specifications.
Whenever the disc brake pad is to be replaced, replace the pads on both rear wheels as a set.
