If your brakes make a bit of noise when the wheel rotates, this is an easy fix.  You want to first inspect the rotor itself, which is the round portion attached to the wheel. If this is not straight, you can bend this back into place with your hand, or with the help of an adjustable wrench, fully compressed on the rotor itself.
