I don't know much about brakes but this sounds like a great idea. We live on a dirt road in the summer and they salt the paved roads in the winter so I end up washing my car a lot. The result is there is often a thin layer of rust which loads up the pads and I have the problem Doug_G is talking about. The trouble with his solution is I have to do it at least once a month to keep my brakes strong. I suspect that stainless rotors are avoided because they don't dissipate heat as well as steel. But who cares I never generate any heat and I could always switch for track days. Does anybody know where I might find stainless or aluminum rotors?
