See Figure 1
- Raise and support the rear of the vehicle on jackstands. Remove the wheel.
- The pads can be inspected through the top of the yoke. However, it is better to remove the pads to measure their thickness.
- Minimum pad thickness is 0.8 in. (2mm). This minimum thickness may disagree with your state inspection laws.
If the pads are worn, always replace all of the pads on both wheels at the same time.
- Check the condition of the rotor while you are about the task of inspecting the pads. If it is scored, cracked or worn beyond the minimum thickness of 0.33 in. (8.6mm) for models through 1983 or 0.35 in. (9.0mm) for 1984-86, or 0.70 in. (18.0mm) for 1987-88, replace it.
REMOVAL & INSTALLATION
See Figures 2, 3, 4, 5, 6, 7, 8, 9 and 10
- Raise and support the rear of the vehicle on jackstands. Remove the wheels.
- Disconnect the parking brake cable.
- Remove the clip at the outside of the pad pins.
- Remove the pad pins. Hold the anti-squeal springs in place with your finger.
- Remove the pads.
To install, perform the following:
- Clean the end of the piston with clean brake fluid.
- Lightly coat the caliper-to-pad, the yoke-to-pad, the retaining pin-to-pad and the retaining pin-to-bracket surfaces with grease. DO NOT allow grease to get on the rotor or pad surfaces.
- Push the piston into place with a screwdriver by pushing in on the piston while at the same time turning it clockwise into the bore. Then, with a lever between the rotor and yoke, push the yoke over until there is clearance to install the pads, equally.
- Install the shims, the pads, the anti-squeal springs and the pins. Install the clip. Note that the inner pad has a tab which must fit into the piston notch. Therefore, be sure that the piston notch is centered to allow proper pad installation.
- Apply the brakes a few times to center the pads. Check the master cylinder fluid level and add fluid, if necessary.
