• Q: How to Service and Repair Brake Calipers on 2001 Chevrolet Lumina?

  A: Before servicing or repairing the brake caliper always take precautions to avoid putting fingers near the caliper piston(s) when using compressed air because a sudden release from the piston can seriously injure you. After cleaning the caliper space put soft materials inside to control piston movement after you blow through with air to let the pistons move out without hurting the parts. The piston will be pushed out after air enters the inlet and exits through the rubber boot. Replace the piston when you detect any scuffs, damage, rust or worn chrome plating on the surface. Keep the caliper bore undamaged when you take off the boot and use plastic or wood tools to extract seals. Use a wooden or plastic tool to remove the piston seal from its caliper bore groove and examine all related components for the same wear signs. Light corrosion in the caliper housing calls for replacement because crocus polishing cannot sufficiently remove it. Inspect bolt boots for cracks that need replacement and check for corrosion in caliper bolts, replacing corroded bolts instead of attempting to clean them. Replace the caliper due to damage when you inspect the seal groove inside the caliper housing. Clean all caliper parts in denatured alcohol while removing the bleeder valve cap and valve from the housing. Clear all passages in the caliper and bleeder valve by blowing filtered non-lubricated air. Thread the bleeder valve onto the caliper housing with the j 36349 front dust boot seal installer tool and tighten it to 13 nm (115 inch lbs.); install the cap onto the bleeder valve afterwards. Fit a new piston seal rubbed with lubricant into the mounting slots of the caliper bore space without twisting it. Then put the lubricated boot onto the piston and apply clean brake fluid to the piston. To install the parts you push the piston bottom first and place the boot into the caliper housing counterbore using j 36349 tool. Complete the setup by adding the caliper.
