BRAKES
9. Measure the inside diameter of the rear caliper. The caliper
body is a 2-step piston. The rear step is measured as well
as the outside step.
10. Inspect caliper piston bore for scratches, severe corrosion,
or galling and replace if necessary.
11. Inspect surface of caliper piston for nicks, scratches, or
damage and replace if necessary.
Assembly
1. Install new O-rings in the slide bolt bushing holes. Be sure
O-ring and seal grooves are thoroughly cleaned of all
residue, or piston may bind in bore. Apply brake fluid to
piston seals and install carefully with a twisting motion to
ease assembly until fully seated.
2. Carefully assemble caliper body, making sure O-rings are
properly positioned in groove. Tighten the caliper anvil
bolts and then torque the anvil bolts evenly to specification.
3. Install brake pads in caliper body with friction material
facing each other. Install the slide pins and the slide pin
retaining rings. Torque the slide pins to specification.
