1. Remove the rear brake caliper from vehicle. Refer to Brake Caliper Replacement - Rear.
Important: 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. Drain the brake fluid from the caliper assembly.
3. 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.
4. Place a block of wood against the inside of the caliper body, opposite of the caliper piston.
5. Direct low pressure compressed air through the caliper inlet hose to remove the caliper piston.
6. Remove the piston dust boot seal (2) from the seal counterbore in the caliper and discard the boot seal.
