OK, so one more question

:
I got the driver rear installed and they look great and also work to stop the car BUT... I'm hearing constant noise from them - just a quiet rub like the pads are rubbing the rotor while driving back and forth in my driveway. Is that normal for newly installed pads and rotors? If yes, how long should I expect for them to break in, and if no how do I go about getting the pads away from the rotor?
