How to overhaul the rear brake calipers on 2003 Chevrolet Trailblazer?

To overhaul the rear brake caliper, start by draining all brake fluid from the caliper and pad the interior with clean shop towels. Be careful not push fingers in front of the Piston while pressing compressed air, as one can get a serious injury. Use only the necessary amount of air pressure to help ease the Piston out of the bore and avoid causing damage. Remove the Piston from the caliper bore as well as the boot and Piston seal without scratching the housing bore or use of metal tools. Then, remove the bleeder valve and cap, guide pins and sleeves from the anchor bracket. Clean the bleeder valve, bore of the caliper, caliper passages, the Piston and the lining contact surface on the anchor bracket using denatured alcohol, then dry all components and blow any excess brake fluid out of the passages using dry and filtered compressed air. Replace the Piston if there is scoring, corrosion, chrome plating damage, and pitting in the caliper bore, polishing light corrosion with crocus cloth if required. Upon replacing the bleeder valve cap, the bleeder valve should be tightened to 12nm 110 inch lbs. Then filter some new clean brake fluid through a paper tissue and lubricate the new Piston seal, caliper bore, and Piston, install the Piston seal making sure it is not twisted and then simply install the boot into the caliper housing bore by hand. Last but not least, insert the Piston into the caliper bore, using your hand to push it down to the bottom of the bore, and attach the boot on the Piston.
