  Q: How to overhaul calipers?

  A: If an overhaul is needed for the Brake Caliper, it is recommended to explore all options before starting the job. New or factory-rebuilt calipers are available on an exchange basis, which makes the process easier. However, if it is decided to rebuild the calipers, ensure that a rebuild kit is available before proceeding. It is important to always rebuild the calipers in pairs and not just one of them. Note that special tools are required to remove the piston from the caliper body for rear calipers on 1979 through 1981 models, so it is advised to remove the caliper assembly and exchange it for a new or rebuilt part from a dealer service department or auto parts store. The removal procedure for front or rear calipers is part of the brake pad replacement procedure. When overhauling the caliper, remove the rubber boot set ring and the rubber boot, and use a wood block to prevent damage when removing the piston. Apply compressed air to the brake fluid hose connection to remove the piston from the caliper. Inspect the mating surfaces of the piston and caliper bore wall, and if there is any damage, replace the entire caliper unit. Remove the rubber seal from the caliper bore using a wooden or plastic tool to avoid damage. On 1982 and later models, push the sliding bushings out of the caliper ears and remove the rubber boots. Wash all components in clean brake fluid or alcohol. Reassemble the caliper using the correct rebuild kit and apply silicone-based grease between the sliding bushing and bushing sleeve. Submerge the new rubber seal and piston in brake fluid and install them into the caliper bore. Install the new rubber boot and retaining ring. Lubricate the sliding bushings and sleeves with silicone-based grease and push them into the caliper ears. Install the dust boots. Finally, install the caliper by reversing the removal procedure and remember to replace the copper sealing washer on the Brake Line union bolt if the caliper has a banjo-type hose connection. Bleed the brake circuit after installation.
