How to Service and Repair the Rear Brake Calipers of the 25 Series on 2003 Chevrolet Avalanche 1500?

All components from the repair kits need replacement before you lubricate rubber parts with clean brake fluid to facilitate easier assembly of the 25 series rear brake caliper. Carefully isolate the brake caliper from your vehicle yet avoid placing fingers in front of the Piston when using compressed air because this step creates significant dangers to your safety. A wooden piece shields pistons before compressed air removes them one at a time from the brake hose inlet fitting followed by removing Piston boots and seals. After unscrewing the brake caliper bleed screw and cap inspect the caliper bores and Piston seal grooves because deteriorated conditions might need replacement of the brake caliper housing. Inspect the mounting bracket for both corrosion and wear damage. Replace the bracket if necessary. Wash away all residue from brake pad guiding surfaces as well as mounting bracket surfaces including parts outside the repair kit with denatured alcohol then dry components with non-lubricated filtered compressed air before blowing out all caliper housing and bleeder valve passages. The brake caliper bleed screw must be installed facing outward before torquing to 12 n.m (106 lb in) then adding a cap to the end. Add a drop of brake fluid to the new Piston seal and brake caliper bore seal groove before setting the seal into place without twisting the element. Brake caliper bore and Piston require lubrication before installing the boot together with Piston while checking that the boot fits correctly into both grooves. After completing this process for the second Piston, return the brake caliper to its original position on the vehicle.
