AAM 1150 axles come with factory disc brakes, so we spent our money rebuilding the calipers, adding EBC Brakes’ Yellowstuff brake pads, and installing 3GD Series Sport slotted rotors. The 13-inch EBC rotors weren’t actually installed in this photo, because we ordered the wrong ones. The correct part number for an ’02 AAM 1150 GM rear axle is GD7216. For those keeping track, the caliper-bracket-to-axle-bracket bolts were tightened to 221 ft-lb, and the smaller caliper-to-caliper-bracket bolts were torqued to 80 ft-lb. And finally, the axleshaft-to-hub bolts were tightened to 148 ft-lb.
