Rear Calipers: Disassembly
WARNING: This page is about a different car, the 2002 Pontiac Firebird and 2002 Chevrolet Camaro. However, it is still accessible from the selected car via links, so may be relevant.
- Remove the rear brake caliper from the vehicle. See REAR BRAKE CALIPER under REMOVAL & INSTALLATION.
- Remove the brake caliper piston from the caliper bore by directing low pressure compressed air into the caliper bore through the fluid inlet hole. See Fig 1 . Using a plastic or wooden tool, remove the piston boot. See Fig 2 . Using a plastic or wooden tool, remove the piston seal. Remove the brake caliper bleeder valve cap.
- Remove the brake caliper bleeder valve. See Fig 3 . Inspect the brake caliper bore and piston seal groove for scoring and corrosion. If badly scored or corroded around the piston seal area, replace the brake caliper housing.
- Inspect the brake caliper mounting bracket guide surfaces for corrosion and wear. Remove and replace the brake caliper mounting bracket if necessary. See Figure . Clean all the residue from the brake pad guiding surfaces on the brake caliper housing and the brake caliper mounting bracket. Clean all the parts not included in the repair kit with denatured alcohol.
- Dry the caliper piston bore and counterbore, and the piston with non-lubricated, filtered air. Blow out all passages in the brake caliper housing and the brake caliper bleeder valve. If light rust or light corrosion are present in the caliper bore, attempt to remove the imperfection with a fine emery paper.
- If the imperfection cannot be removed, replace the caliper assembly. If cracks, scoring, pitting, excessive rust, and/or excessive corrosion are present in the caliper bore, replace the caliper assembly.
