Brake rotors and disc brakes should be inspected all the way around the surface on both sides. Look for any concentric scoring, grooves or obvious defects. If any defects are found replace defective part immediately. Look for any brake rotor discoloration. This may be a sign of the brakes overheating. At this point a profession brake inspection by a brake repair mechanic is needed.
