Helpful Expert Reply:
They sure are. The buzzing or humming sound means that the magnets that grab the armature surface of the brake drum and actuate the brakes are active and are receiving power from the brake controller. The humming noise does not indicate a problem.

My brakes do buzz but they just barely drag. If they are out of adjustment will they do that?
