There is an electrical motor sound
when I press on the brake pedal or
activate the park brake switch. Is this
normal?
Yes, those sounds are the electronic
brake booster or the electronic park
brake operating.
Note:
Brake dust could accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See
