This got to be a joke, the rotors are steel, the brake pads are composite, I can see the pistons taking a set but they have boots. The slight out of round will free them in a couple of rotations. There is nothing anything to rust to. As another post stated, the emergecy cable could rust in the sheath, I doubt it. Sears knows less than PepBoys and Jiffy lube. If it sat out for years with the emergency on, it might not retract.
