i noticed today on a bunch of cars parked at a railroad station that their rotors were all rusting. we had lots of rain in the NE recently but today it cleared up and sun was shining. i then looked at my rotors (2002 taco, which were parked just as long as any other car) and the rotors were nice and shiny, no rust.
so what's the deal, other manufacturers using rotors that have lots of iron in them, much more iron than what Toyota's get ???
