Front Caliper
- Remove caliper from vehicle. See FRONT BRAKE CALIPER under REMOVAL & INSTALLATION. Remove caliper bushings and inspect. Replace bushings if nicked, worn or damaged. Using a clean shop towel to pad interior of caliper, remove piston using compressed air at caliper inlet port. Inspect piston for scoring, nicks, corrosion and worn or damaged chrome plating. Replace as necessary.
- Using nonmetallic tools to avoid scratching, remove boot from piston and piston seal from caliper. Inspect caliper bore for scoring, corrosion, nicks and wear. Using crocus cloth, clean out caliper bore. If corrosion will not clean off of seal groove, replace caliper housing.
- Clean all parts with denatured alcohol. Dry with compressed air. Blow out passages in caliper and bleeder valves. Install bleeder valves and tighten to specification. See TORQUE SPECIFICATIONS . See Figure.
- Lubricate NEW piston seal and install into caliper bore groove. Lubricate boot and install onto piston. Install piston and boot into caliper bore, pushing piston to bottom of caliper bore. Using Dust Boot Seal Installer (J 26267), seat boot into caliper housing. Lubricate beveled end of bushings with silicone grease. Install bushings into mounting bores, beveled end first.
CAUTION:
Do not place fingers in front of caliper piston when applying compressed air to remove piston. Serious injury may result.
