The friction with the pads will wear the rust off. Like I said earlier, I've never had a problem with rust build up because all my cars are garaged, and even when they do spend a night outside at work, I USE my brakes when I drive so whatever surface rust might be there (which isn't much) is gone within a few minutes.
Ahhh I see... and I use my paddle shifters to slow down a lot.. Ok I will use heavier brakes more often and see it that helps any. Thanks.
