It may be the brakes or I have seen inner wheel bearing seals get dry and because whistle sound. There can be a stick or road debris stuck underneath and is rubbing on the axle. If it only happens when you're moving then it wont be a vacumn line and if it's there when you aren't moving then it wont be brakes or seals,maybe a belt sound.
