Hey! lift the car 1 tire at a time, remove the rotors soak them in white viniger for a few hours a piece. this will not only remove the rust from the break pad contact surface but it will also loosen if not remove all the rust from the holes around the edges. after this measure the rotors in mm to see if they match or are close to matching stock rotor specs. if you get a nice shiny rotor with no pitting in the metal or cracks. even hair pin cracks are no good! then you are ok to re install. The viniger chemically re-bonds "fuses" the surface layers of atoms in the steel. at the same time boils all the oxidation of the surface layers.
