glad you fixed it, I have the same issue when wheelin when getting a rock stuck in between that plate & rotor.

one thing I do want to say, is don't auto think you need to replace the rotor when you do brakes, you can "TURN" the rotors if it is still within spec and then you can slap new pads on it. this will prevent squealing. Any brake shop or auto part store can check if with in spec.
