Q: How to replace the rear brake calipers bracket on Cadillac Escalade?
A: To install the new rear Brake Caliper Bracket start by lifting and securing the vehicle before removing the tire and wheel set up. Unbolt both parts of the quarter shaft shield before you can remove it. Install the brake caliper on mechanic's wire support and keep the hydraulic brake hose connected as you disconnect the two mounting bolts of the brake caliper. Loosen and support the brake caliper before removing both bolts from the caliper mounting bracket. Slide away the brake pads with their anti-rattle clips from the bracket. Install the brake caliper first by putting the anti-rattle clips and disc brake pads on the brake caliper mounting bracket. Clean the bolt threads with brake parts cleaner before applying threadlocker gm p/n 12345493 (Canadian P/N 10953488). Remove all original adhesive patch from these bolts. Mount the brake caliper on its base by tightening bolts to 148lb-ft torque. Follow the same process for the remaining 2 bolts and install the brake caliper in position before tightening them to 42 n.m (31 lb ft). Set the quarter shaft shield in place again and tight both metal fasteners to 25 n.m (18 lb ft). Realign the tire assembly then lower the vehicle. After switching off the engine apply the Brake Pedal halfway then release it slowly and repeat this several times to perfectly seat the brake pads and brake pistons.
Q: What Tools Are Required to Service and Repair Rear Brake Calipers on Cadillac CTS?
A: Service and repair work on the rear brake caliper needs these items: universal driver (J8092) and caliper boot seal installer (J 45507). First take out the brake caliper from the vehicle then put clean cloths inside the caliper storage for Piston removal. Air at low pressure helps the pistons exit their bores but the technician should not cause any harm. Extract the Piston dust boot seal and Piston seal using a wooden or plastic tool and detach the brake caliper bleeder valve cap followed by the valve itself. Check the Brake Caliper Bracket for damage and rust symptoms then switch it if needed. Clean the Brake Caliper Piston bore and seal counter-bore with denatured alcohol then blow dry them with non-oiled filtered air. Replace the brake caliper unit when you find any breaks, scuffs, pits or heavy rust on its Piston and bore area. Load the brake caliper bleeder valve and fasten it to 14 n.m (124 lb in) torque before putting on the bleeder valve cap. Put delco supreme 11 brake fluid (part:12377967) into the new Piston seal and push it into the caliper bore seal groove without twisting it. Before setting the Piston in place apply brake fluid inside both the bore and Piston. Put the dust boot seal inside the caliper with the universal driver tool when using the caliper boot seal installer tool to make sure the seal fits perfectly into its groove. Reapply the calibrated component onto its regular position.
Q: How to replace the rear brake calipers on Cadillac XLR?
A: Begin by checking the brake master cylinder reservoir fluid level before caliper replacement starts. The fluid level should guide your actions: you need no removal when at the midpoint yet need to drain fluid to the midpoint when the level is above the correct spot. Begin by safely lifting the vehicle and removing the tire along with wheel assembly. Remove the brake caliper inlet fitting bolt and brake hose from the caliper as you discard the two copper brake hose gaskets that might stick to the caliper or hose end. Secure your plug to the brake caliper opening then the brake hose before you remove the brake caliper guide pin bolts to extract the caliper from the mounting bracket. Check both caliper slide boots for signs of damage. Change the slides and boots when required. Fit the brake caliper onto its mounting bracket before tightening the brake caliper guide pin bolts to 31 N.m (23 lb ft). New copper brake hose gaskets need installation plus the brake caliper inlet fitting bolt needs tightening to 45 N.m (33 lb ft) when the plugs from the brake caliper opening and brake hose are removed. Following fluid bleeding of the hydraulic brake system reinstall the tire and wheel assembly before lowering the vehicle.
