Is it normal for my brakes to make noise?Occasional brake noise is normal. If a metal-to-metal, continuous grinding, or continuous squeal sound is present, the brake lining could be worn-out. Have your vehicle checked as soon as possible.There is an electrical motor sound after I press the brake pedal or activate the electric parking brake. Is this normal?Yes, those sounds are from the brake system operating.
Note:
Brake dust could accumulate on the wheels, even under normal driving conditions.Some dust is normal as the brakes wear and does not contribute to brake noise. See
Cleaning Wheels.
