REMOVAL & INSTALLATION
See Figures 1, 2, 3, 4 and 5
- Check the level of fluid in the master cylinder. If the fluid is near the maximum level, use a clean syringe to remove fluid until the level is down well below the lip of the reservoir.
When the caliper pistons are retracted into the caliper the brake fluid level will rise. Therefore, it may be necessary to remove some brake fluid from the master cylinder reservoir.
- Raise and support the vehicle safely.
- Remove the rear wheels.
- Release the parking brake and remove the cable mounting bracket bolt. Remove the bracket and the lock spring.
- Remove the lower slide pin bolt and pivot the caliper body upward.
- Remove the pad springs, pad shims and the brake pads.
- Clean the piston end of the caliper body and the area around the pin holes.
- Using a suitable pair of needle nose pliers, carefully turn the piston clockwise, while pushing the piston into the caliper body. Use care not to damage the piston boot.
A variety of special tools are available aid in retracting the rear caliper piston
- Coat the pad contact area on the mounting support with a silicone based grease.
- Install the pads, shims and the pad springs. Always use new shims.
- Position the caliper body in the mounting support and tighten the pin bolt to 28-38 ft. lbs. (38-52 Nm).
- Operate the parking brake several times to properly seat the brake pads.
- Install the wheels and lower the vehicle.
- Verify proper brake operation before attempting to move the vehicle.
You should be able to check the pad lining thickness without removing the pads. Check the Brake Specifications chart at the end of this section to find the manufacturer's pad wear limit. However, this measurement may disagree with your state inspection laws. When replacing pads, always check the surface of the rotors for scoring, hard spots (black discolorations), and/or wear. Also check that the rotors are within specifications for thickness, parallelism and run-out. If any problems exist with the brake rotor the rotor must be resurfaced or discarded.
