Front 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 brake caliper from the vehicle. See FRONT BRAKE CALIPER under REMOVAL & INSTALLATION.
- Remove the brake caliper pistons 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 boots. See Fig 2 . Using a plastic or wooden tool, remove the piston seals.
- Remove the brake caliper bleeder valve cap. See Fig 3 . Remove the brake caliper bleeder valve. Inspect the brake caliper bores and piston seal grooves 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. See Fig 4 . Remove and replace the brake caliper mounting bracket if necessary. 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 all the parts with filtered non-lubricated, filtered compressed air. Blow out all passages in the brake caliper housing and the brake caliper bleeder valve. Inspect the caliper bores for cracks, scoring, pitting, excessive rust, and/or excessive corrosion.
- If light rust or light corrosion are present in the caliper bores, attempt to remove the imperfection with a fine emery paper. If the imperfection cannot be removed, replace the caliper assembly.
CAUTION:
DO NOT use abrasives to clean the brake caliper pistons.
