  Q: How to overhaul brake calipers on Chevrolet Cavalier?

  A:

  Begin brake caliper overhaul by taking it out of the vehicle. Use low air pressure to push compressed air into the caliper bore through its fluid entry point to release the brake piston. Gently pull out the piston dust boot seal using a small plastic tool from its spaces in the caliper while discarding it. Remove the piston seal from the caliper opening to finish the process. Take off the bleeder valve and its cover from the caliper . You should avoid abrasive materials when cleaning the Brake Caliper Piston. Clean the brake caliper parts with denatured alcohol or its equal before drying them with filtered air since no lubricant. Check the end of the caliper for damage such as breaks, marked areas, abrasions, deep rust or corrosion. Wash away light rust with fine sandpaper but replace the caliper when rust stays. The brake caliper assembly requires replacement when any crack, deep rust marks, rough surface damage or extreme rust appears. Evaluate the caliper piston for damage on its surface and chrome plating to determine if replacement is needed. To install the new piston seal add delco supreme 11 lubricant (GM P/N 12377967 equivalent or DOT-3 brake fluid) from a sterile container before fitting it into the caliper bore. Slide the caliper piston through the bore before setting the new piston dust boot seal properly on it. A caliper piston dust boot seal installer tool or an equal device helps to properly seat the dust boot seal into its designated diameters. After connecting the bleeder valve, tighten it securely and put the front brake caliper back into the car position.

  Q: How to replace the Brake Calipers on Chevrolet Cavalier?

  A:

  Brake caliper replacement requires removing 2/3 of brake fluid from the master cylinder assembly before raising and supporting the vehicle. Mark the wheel's alignment with the hub and bearing system before wheel rebalance to disassemble the tire and wheel assembly and secure the rotor to the hub with 2 wheel nuts. Drive the Piston into the caliper bore utilizing a large c-clamp to open up space between rotor and linings by clamping against the outboard shoe until the caliper can be removed from the rotor. Detach the inlet fitting bolt from the caliper assembly during complete unit repair. The inlet fitting should not be removed when the caliper replacement involves only lining changes. Protect fluid loss and contamination by plugging both the caliper housing inlet fitting and the brake hose. Start by removing the caliper mounting bolts together with sleeve assemblies before you take the caliper away from its connection to the rotor and knuckle while maintaining physical contact between the caliper and brake hose to prevent damage. When removing the caliper assembly for unit repair use wire hook suspension from the strut. Test the mounting bolts and sleeve assemblies for corrosion before inspecting the bushings for cuts and nicks as you install new parts. Cleaning corroded areas through polishing is unacceptable. Silicone grease should be generously applied to the inside diameter of the bushings before mounting bolts and sleeve assemblies get installed. Mount the caliper onto the rotor inside the knuckle after tightening its mounting bolt and sleeve assemblies to 51 nm (38 ft. Lbs.). Reinstall the inlet fitting and tighten it to 44 nm (32 ft. Lbs.). Before lowering the vehicle install the wheel and tire assembly after removing wheel nuts from the hub and bearing assembly then installing retaining nuts in their proper order. Add proper brake fluid to the master cylinder before installing the inlet fitting on the caliper. Then check the brake fluid level and pedal feel once more.
