The procedure is to remove the brake caliper, the brake caliper piston, the piston dust boot seal, the piston seal, and the bleeder valve, clean the brake caliper piston bore and seal counterbore and the caliper piston, dry the caliper piston bore and counterbore, and the piston, inspect the caliper bore, remove the imperfection with a fine emery paper, replace the caliper assembly and inspect the caliper piston for cracks, scoring, and/or damage to the chrome plating.
