We have been having an issue with my father-in-law's 01 3500 dually. He's been going through brakes like nothing, and we cannot figure out exactly why. He doesn't ride the brakes, no sudden stops, all in all, doesn't abuse them. We've put two sets of rotors and pads on the rear of the truck, and he's sick of doing that. I was curious if there was a heavier duty option to use.
