  Q: How to replace the front brake caliper bracket on Cadillac STS?

  A:

  You must first jack up the vehicle and support it to replace the front Brake Caliper Bracket. Then you need to remove the wheel and tire unit. Apply a second wrench tool on the brake caliper guide pins to loosen the guide pin bolts . Secure the brake caliper with heavy mechanic wire to stop bending pressure on the rubber brake line. Uninstall the brake caliper first and then proceed to remove the outer and inner Brake Pads plus their spring and finally the brake caliper bolt bracket. Inspect the disc brake hardware. Start the installation with Brake Caliper Bracket insertion. Install threadlocker gm p/n 12345493 (Canada P/N 10953488) on two-thirds below the threads of lower caliper bracket bolts. Clean the threads thoroughly then apply the threadlocker and wait 10 minutes for it to cure. Attach the Brake Caliper Bracket bolts with 130 nm torque (96 lb ft) before adding Brake Pad springs, an outer Brake Pad, and an inner Brake Pad. Wash and apply threadlocker to the caliper bracket bolts only before you put the brake caliper to the caliper bracket. Clamp a back up wrench onto the caliper guide pins as you attach the guide pin bolts and tighten them to 32 nm (24 lb ft). Put the tire and wheel assembly back in place afterward.

  Q: How to replace the rear brake caliper bracket on Cadillac STS?

  A:

  Start by installing heavy mechanic's wire as support for the brake caliper before you detach it from its hydraulic flexible brake hose during replacement of the rear Brake Caliper Bracket. Start by taking off the brake caliper from its Brake Caliper Bracket while keeping the hydraulic brake flexible hose intact. Begin by removing Brake Pads and Brake Pad retainers from the Brake Caliper Bracket followed by removing caliper bracket bolts to disconnect the rear Brake Caliper Bracket. Test the brake mount hardware through inspection before replacing the Brake Caliper Bracket when damage or cracking occurs. Before installation you must clean the lower caliper bracket bolts and threaded holes with denatured alcohol before applying gm p/n 12345493 thread locker (Canada P/N 10953488) over the first two-thirds of the bolt length while checking that threads remain completely filled. The threadlocker requires ten minutes of curing time before the installation of Brake Caliper Bracket bolts which must then receive 120 n.m (88 lb ft) of torque. You should reinstall the Brake Pad retainers along with brake pads onto the Brake Caliper Bracket before installing the brake caliper.
