If the rotor has become extremely hot, the braking surface may exhibit blue marks or bands. See figure 7 for examples of these marks. This condition may be caused by continued hard stops, improper brake balance, improper brake caliper clearance, operation, or adjustment. The cause of overheating should be determined and corrected. It is not necessary to replace the rotor as long as it meets the proper dimensional specifications for runout and thickness.
