No its a grinding sound definatly not normal.
Parking brake seems fine not to tight(If it was it would have worn down by now)Also it grabs low,probobly needs tightened .
Last time I checked the temp of rotor at my brothers shop and they were normal.

I don't think the sound is normal either - I was trying to get at if there are other issues you can feel versus just hear. The fact that you mentioned that the parking brake grabs low is a sign to me that the parking brake cable is not moving freely in its guide (not releasing properly), the parking brake is not adjusted properly, or the parking brake shoes are worn. Did you try what I suggested - tugging hard on the parking brake cable underneath the driver's side. It will feel tight to start with. If you tug on it and it frees up, you have a parking brake cable problem.
