I set rotor up on car as described above. Was able to get surface reasonably smooth and most of rust removed. But there was still some pitting and in particular in one or two spots across the braking surface. A proper machine could no doubt have removed this, but rotor was now just over 9mm and this was just the first side. Called store and new rotors will be here on Monday (Zimmerman)!
