• Q: How to replace the rear brake caliper bracket (RPO J5, JL9) on 2006 Buick LaCrosse?

  A: Start replacing the rear Brake Caliper Bracket (RPO J5, JL9) by removing the brake caliper then hanging it with heavy mechanic wire without severing the hydraulic brake hose connections. You need to remove both brake pads from the caliper bracket before taking off the Brake Pad retainers from the same part. Remove the Brake Caliper Bracket by turning off its bolts and pulling it away from the caliper. Brush off rust at the Brake Caliper Bracket with wire and check the brake mountings and hardware. Clear all threadlocker residue and debris from the caliper bracket threaded holes using a quality alcohol cleaner before installation. Apply threadlocker gm p/n 12345493 (Canadian P/N 10953488) to two-thirds of the bolt threads after cleaning it well. Insert the bolt through the bracket but leave no space between the threadlocker and the bracket as it requires ten minutes to cure. Set the Brake Caliper Bracket over the designated area and bolt it into position by tightening the mating bolts to 130 nm (96 ft. Lbs.). Nourish brake caliper pin bolts with silicone lube before you put on Brake Pad retainers and high temperature pads into the caliper bracket followed by the overall brake caliper assembly.
