Brake Caliper OVERHAUL on Acura Integra?


The procedure is as follows :---

Some vehicles may be equipped dual piston calipers. The procedure to overhaul the caliper is essentially the same with the exception of multiple pistons, O-rings and dust boots.
  1. Remove the caliper from the vehicle and place on a clean workbench.

NEVER place your fingers in front of the pistons in an attempt to catch or protect the pistons when applying compressed air. This could result in personal injury!

Depending upon the vehicle, there are two different ways to remove the piston from the caliper. Refer to the brake pad replacement procedure to make sure you have the correct procedure for your vehicle.
  1. The first method is as follows:
    1. Stuff a shop towel or a block of wood into the caliper to catch the piston.
    2. Remove the caliper piston using compressed air applied into the caliper inlet hole. Inspect the piston for scoring, nicks, corrosion and/or worn or damaged chrome plating. The piston must be replaced if any of these conditions are found.

  1. Carefully loosen the brake bleeder valve cap and valve from the caliper housing.
  2. Inspect the caliper bores, pistons and mounting threads for scoring or excessive wear.
  3. Use crocus cloth to polish out light corrosion from the piston and bore.
  4. Clean all parts with denatured alcohol and dry with compressed air.
To install:
  1. Lubricate and install the bleeder valve and cap.
  2. Install the new seals into the caliper bore grooves, making sure they are not twisted.
  3. Lubricate the piston bore.
  4. Install the pistons and boots into the bores of the calipers and push to the bottom of the bores.
  5. Use a suitable driving tool to seat the boots in the housing.
