Thanks. I was thinking (maybe hoping) that it was something like that. So, other than doing some hard braking and then seeing if the groaning goes away, what else should I do?
- Nothing; just do some hard braking if the sound comes back.
- Replace the rotor
- Replace both rotors
- Something else
(Gotta love the auto-number feature here.)
I’ll report the results in a few days. (I expect not to drive the car today or tomorrow,) If the groaning persists, I’ll ask for more advice.
