• Q: How to replace the rear brake disc on 2005 Cadillac XLR?

  A: The process to replace rear brake rotors requires first releasing the park brake followed by vehicle elevation supported by safe stands before proceeding to remove tire and wheel combinations. The park brake cable should be disconnected from the brake apply lever and then use a c-clamp (J 41013) to pressurize the Piston until the caliper slides off the rotor. After taking off the c-clamp set the brake caliper on heavy mechanic's wire to maintain the hydraulic flexible brake hose safety. Separate the caliper bracket bolts but maintain connection of the brake flexible hose bolt before taking off the brake caliper mounting assembly with its bracket while ensuring the hose remains under zero tension. Relocate the brake rotor to match the wheel studs before carefully detaching it from its position. Gentle rotation during the process may help if removal requires pulling outward. Thorough cleaning of hub/axle flange rust and contamination requires the wheel hub resurfacing kit (J 42450-A) while rotor cleaning uses the rotor resurfacing kit (J 41013). The maintenance process requires checking mating surfaces for foreign particles and reconnecting the park brake cable followed by proper adjustment of park brake shoe clearance with the brake rotor drum-in-hat area. Use the matchmark for proper orientation when installing the brake rotor to the hub/axle flange before measuring its lateral runout (LRO) to guarantee peak brake functionality. Adjustments should be made when the lro measurement surpasses the specified values. The installation of brake caliper and bracket assembly must be performed onto the suspension knuckle before reattaching tire and wheel components while lowering the vehicle and optionally performing pad and rotor burnishing.
