You shouldn't hear a whistling sound, I would jack up the car, properly support it and remove the wheel, then rotate the wheel and look/listen for any rubbing sound, perhaps a brake pad shim has become dis located or the brake disc dust/water shield is slightly rubbing something but you may see a mark or small metal shavings on your examination.
