what does it mean when your rotors are metal to metal? The cause of that requires new rotors?

The brake pads have rivets in the material attaching them to the calipers. When the pads wear too much, the metal rivets become exposed and gouge in to and dig trenches in the rotors, only the pad should make contact on the rotor, hence metal on metal. If the gouges are not too deep, the rotors may be used as is or machine-planed to a good surface. There are specifications on how much can be machined off of a rotor and remain legal and effective
