Brake Caliper: Service and Repair
Rear
Brake Caliper Overhaul - Rear
1. Remove the rear brake caliper from vehicle.
If the brake caliper was leaking brake fluid from the REAR of the caliper past the integral park brake actuator shaft seal, replace the brake caliper
assembly. The park brake integral mechanism contains a non-serviceable seal which may be allowing brake fluid to leak past it and into the
non-serviceable integral park brake mechanism.
2. Remove the caliper sleeves from the caliper mounting holes.
3. Remove the brake caliper sleeve dust boots.
4. Using a small wooden or plastic tool, carefully remove the brake caliper piston dust boot seal retaining ring from the groove in the caliper seal
counterbore.
5. Using a spanner type wrench, rotate the brake caliper piston (2) counterclockwise to remove the piston with the dust boot seal (3) from the caliper
(1).
