I just finished a complete brake upgrade with GM 2500 Pads front and back. I now have 110,000 miles on my truck with the Original Brakes. I know because I checked the part #'s and they were with the factory lock tight on the bolts as well. Remember I have 4.56 gears in the truck now for towing with a 13,000 lbs Load. So I went with Power Stop calipers, Bi Directional Rotors left and right side rotors and GM front and rear pads. Then I topped it off with a new set of BFGoodrich KO 2 275-70R-18 126E tires and new wheels plus I had 2 in. 6060 aluminum billet spacers for the rear custom made so that my hub centers were tight fit for the rotors and wheels. Here are some pic's! Donald
