Caliper Overhaul - Rear Disc Brakes: Assembly
CAUTION:
Keep alcohol and brake fluid away from eyes, as serious injury may result. Keep rubber seals and brake parts away from oil. Oil can cause seals to swell and deteriorate, and braking system could become inoperative.
NOTE:
Do not use a hone or any other procedure to remove material from piston or caliper bore.
- Clean all parts with denatured alcohol or brake fluid. Dry parts with unlubricated compressed air, and blow out all passages in caliper and bleeder valve. Inspect piston and caliper for scoring and corrosion. Replace any components that show these conditions. Insert bleeder valve and dust cover. Tighten bleeder valve to 11 N.m (97 INCH lbs.). Lubricate new inner seal and caliper bore with brake fluid. Install inner seal into groove in caliper bore.
- Install outer seal into caliper bore. Lubricate piston with brake fluid. Install piston into caliper. Install outer seal into piston groove. Apply steady hand pressure until piston is seated in bore. Inspect brake shoe linings for minimum thickness. Inspect guide pins and boots. See Fig 3.
- If boots are damaged, or if guide pins do not slide easily, replace these parts. Lubricate guide pins with a lithium soap base glycol grease or other grease which will not deteriorate or swell rubber boots. Install caliper.
