As uniberp says, I was not talking about the rotors being parallel. But since you mention it, the driver's side does have some run-out. I can't feel it in the pedal though, and the front brakes are helping me to stop, rather than massaging the sole of my foot as they did before. I suspect the machine shop did a good job of mounting and grinding the rotors, and then I did a crude job of driving out an old bearing race and installing a new one, and this partly undid their good work. It stops well now. You can feel the brakes gripping rather than skating along. But maybe it would be best to take that rotor in for another grind.
