Removal & Installation
- Raise and support vehicle.
Remove the wheel mounting nuts, then the tire and wheel assembly.
NOTEIn some cases, it may be necessary to retract caliper piston in its bore a small amount in order to provide sufficient clearance between shoes and rotor to easily remove caliper from knuckle. This can usually be accomplished before guide pin bolts are removed, by grasping rear of caliper and pulling outward working with guide pins, thus retracting piston. Never push on piston directly as it may get damaged.
Remove the two caliper guide pin bolts.
Remove the caliper assembly from the brake adapter by first rotating bottom of caliper away from the rotor, then lifting the caliper (with shoes) away from upper adapter abutment.
- To prevent the weight of the caliper from overextending and damaging the brake hose while the caliper is off mount, hang brake caliper from vehicle using wire or cord.
- Remove any clips retaining the brake rotor to the wheel mounting studs.
- Remove the brake rotor from the hub and bearing.
Inspect the disc brake pads and parking brake shoes before installation.
- Clean the rotor mounting face of the hub and bearing to remove any dirt or corrosion.
- Install the brake rotor over the studs on the hub and bearing.
Make sure the abutment shims are in place on both slide abutments of the caliper adapter.
WARNINGUse care when installing caliper assembly onto adapter so guide pin bushings and sleeves do not get damaged by mounting bosses on adapter.
- Retract the caliper guide pins to clear mounting bosses on the caliper adapter when installing caliper.
Install the brake caliper in the opposite way it was removed. Starting with the upper end, carefully position the caliper and brake pads over the brake rotor and align the outboard pad's upper edge with the caliper slide abutment. Rotate the lower end of the caliper into mounting position on adapter.
WARNINGExtreme caution should be taken not to cross-thread caliper guide pin bolts when they are installed.
- Carefully install the caliper guide pin bolts. Tighten bolts to 17 ft. lbs. (23 Nm).
- Install the tire and wheel assembly. Install and tighten wheel mounting nuts to 100 ft. lbs. (135 Nm).
- Lower vehicle.
- Pump brake pedal several times to ensure vehicle has a firm brake pedal before moving vehicle.
- Check and adjust brake fluid level as necessary.
- Road test vehicle and make several stops to wear off any foreign material on brakes and to seat brake pads.
