REMOVAL & INSTALLATION
See Figure 1
- If equipped with an air bag, disconnect the negative battery cable and properly disable the Supplemental Restraint System (SRS), as detailed in Chassis Electrical .
- Loosen the lug nuts, then Raise and safely support the vehicle on jackstands.
- Remove the rear wheel.
- Remove the 2 caliper mounting bolts and remove the caliper from the bracket.
- Remove the pads, shims and pad retainers.
- Clean the caliper thoroughly removing any dirt or dust. Check the brake rotor for grooves or cracks; machine or replace, as necessary.
- Install the pad retainers. Apply a disc brake pad lubricant to both surfaces of the shims and the back of the disc brake pads. Do not get any lubricant on the braking surface of the pad.
- Install the pads and shims.
- Use a suitable tool to rotate the caliper piston clockwise into the caliper bore, enough to fit over the brake pads. Lubricate the piston boot with silicone grease to avoid twisting the piston boot.
- Install the brake caliper, aligning the cut-out in the piston with the tab on the inner pad. Tighten the mounting bolts.
- Install the wheel. Lower the vehicle.
- Check the fluid in the master cylinder and add as required. Depress the brake pedal several times to seat the pads.
- If equipped, enable the SRS system and connect the negative battery cable.
See Figure 2
View the pads (both inner and outer) through the cut-out in the center of the caliper. Remember to look at the thickness of the pad friction material (the part that actually presses on the disc) rather than the thickness of the backing plate which does not change with wear. Replace the brake pads if the remaining lining is below 3 / 32 in. (2.4mm).
Remember that you are looking at the profile of the pad, not the whole thing. Brake pads can wear on a taper which may not be visible through the window. It is also not possible to check the contact surface for cracking or scoring from this position. This quick check can be helpful only as a reference; detailed inspection requires pad removal.
