Mazda Mazda3 Noise due to brake rotor grinding against caliper bracket

(9 reports)

If you hear a constant grinding noise from the front brakes, even when not pressing the brake pedal, it is possible the wheel hub has shifted in the steering knuckle causing the brake rotor to grind against the caliper bracket. The hub will need to be inspected (replaced if necessary) and Mazda has a repair procedure for this concern.
