• Q: How to overhaul brake calipers on 2003 Chevrolet Tracker?

  A: An overhaul of the brake caliper begins by lifting and supporting the vehicle followed by tire and wheel removal. Disconnect the caliper from the vehicle but keep your fingers away from the Piston when using compressed air for safety purposes and put on safety glasses for eye protection. Apply only a minimal level of air pressure to extract the Piston through the bore because high levels could harm a broken Piston. Insert a block of hard wood or a shop cloth into the caliper interior to catch the Piston which can escape when applying compressed air at the caliper brake hose connector hole. Extract the Piston seal from the caliper by using a flat plastic tool after removing its rubber boot from the caliper groove. Separate the caliper bleeder valve from its position while minimizing exposure of eyes and skin to brake fluid before cleaning the caliper set ring and Piston along with the caliper cylinder bore in brake fluid. Thoroughly examine the Piston for scoring, corrosion and chrome plating damage and replace it in case of discovery. Then check for similar corrosion on the caliper cylinder bore using a crocus cloth to lightly polish away the corrosion. Replacement of the caliper becomes necessary when corrosion does not resolve itself. Begin assembly stages by first inserting the new Piston seal in the caliper bore before applying the new Piston boot onto the Piston followed by feeding the Piston into the caliper . Position the Piston boot into the caliper groove while avoiding Piston displacement from the cylinder then verify proper boot placement through Piston pulling. Push the Piston into the caliper until it seats fully in the bore before adding the bleeder valve installation. Install the caliper to the vehicle before putting on the wheel components then lower the vehicle before bleeding the brake system.
