I watched a video demonstrating how to check the runout with a dial meter. Unexpectedly, the runout was measured out of range for a brand new replacement rotor! It wasn't a problem with the hub surface the rotor mates to, but the rotor itself. They returned it as defective.
I suspect that most brake jobs don't take the time to setup a runout test for new out-of-the-box rotors. I am wondering if anyone performs this extra step to verify the quality of a new rotor?
