INSPECTION



See Figure 1

Fig. Fig. 1: Inspect the pad for thickness, even wear and signs of cracking. This pad is in good condition

  1. Minimum pad thickness is 0.8 in. (2mm). This minimum thickness may disagree with your state inspection laws.
  2.  

If the pads are worn, always replace all of the pads on both wheels at the same time.

  1. 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.

Fig. Fig. 10: When installing the pad(s), make sure the tab seats properly in the notch

  1. To install, perform the following:
    1. Clean the end of the piston with clean brake fluid.
    2.  
    3. 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.
    4.  
    5. 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.
    6.  
    7. 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.
    8.  
    9. Apply the brakes a few times to center the pads. Check the master cylinder fluid level and add fluid, if necessary.
