Can I reuse old brake pads on new rotors?

Reusing old brake pads on new rotors prevents the surfaces from mating properly, leading to uneven contact and lines or pitting forming on the new rotor. Because old pads wear into the shape of your previous discs, they cannot seat flat against a brand new rotor surface.
