It may be that no one has done any brake upgrades since they are as scarce as hen's teeth, unless you put monster 20" + wheels on the truck. That may be why you aren't getting a response. I wish there were a kit that would work with the stock wheels. Mark Craig (i think) is a supporting vendor that has talked about better stock-type rotors with Hawk pads that supposedly increases braking performance, but at only 43k miles on my '01 I still don't need brakes yet, but Mark will be my first call when I do.
