How to overhaul the rear brake calipers on 2004 Buick Park Avenue?

Question

Accepted Answer

Start the brake caliper rear overhaul process by removing it from the vehicle. The presence of brake fluid leaks from the rear section necessitates replacing the entire brake caliper assembly since the non-replaceable seal might be responsible. Extract the Brake Caliper Piston dust boot seal retaining ring with a small wooden or plastic tool after you uninstall the caliper sleeves and dust boots. Through counterclockwise rotation using a spanner wrench you can separate the Brake Caliper Piston and dust boot seal away from the caliper . The car mechanic should handle both the piston dust boot seal and the piston seal separately while taking away the bleeder valve from the caliper body part. Check that the park brake actuator lever return spring is positioned correctly before conducting a complete inspection of the integral park brake's functionality. The brake assembly requires replacement when the integral mechanism binds or seizes. Use a combination of denatured alcohol to clean the Brake Caliper Piston bore and all other linked surfaces alongside the seal counterbore and piston and sleeves before using non-lubricated filtered air for drying. Check the caliper bore for all forms of damage including cracks and scoring and pitting and rust and corrosion. Use fine emery paper to attempt repair of imperfections but replace the caliper assembly if the repair is unsuccessful. When inspecting the Brake Caliper Piston and sleeves for damage you must replace both components right away. First remove the nut connecting the park brake lever to the actuator shaft followed by eradicating the lever and spring that operates the return to park position. Tapping the service tab of the park brake actuator shaft seal out of its seat requires a flat bladed tool or punch and disposal of the damaged item. Replace the caliper assembly if the inspection reveals any pitting, rusting or excessive corrosion on the sealing surface. A park brake actuator lever and return spring replacement should occur if you detect any signs of wear or deformity. Put a thin layer of high temperature silicone brake lubricant on the new park brake actuator shaft seal surface before installing this seal and reattaching the return spring and park brake lever. Apply delco supreme 11(R) brake fluid (GM P/N 12377967; Canadian P/N 992667 or equivalent DOT-3 type brake fluid) to the new piston seal before placing it in the caliper bore along with the new dust boot seal. Use a bore to insert the caliper piston while rotating it clockwise until it sits completely before placing the retaining ring across the dust boot seal. Install the bleeder valve before you add high temperature silicone brake lubricant to the sleeves and mounting holes and then install the dust boots and sleeves. Throughout the hydraulic brake system bleeding procedure you should inspect for leaks after you complete attaching the brake caliper to the vehicle. Any leakage that happens from the front beyond the piston dust boot will require replacement of the caliper piston assembly.
