I bought this truck new and the brakes have always sucked. So I have been doing some reading and decided to do something about the problem. I purchased new rotors 2500 calipers and new pads. Also changed wheel cylinders in the rear for one ton. What a huge difference. Last week I was towing a utility trailer with a four wheeler and returning home from a hunting trip when it pushed me almost through a stoplight. (wake up call) All I want to say is thanks for all the ideas for brake upgrades. This site is a tremendous help.
