Brakes that need repair may squeal until you come to a full stop or when you release the brake pedal. That means that your brake wear indicators may be scraping against the rotors. A grinding and growling sound of metal on metal means that the brake pads are completely gone. You should have a certified brake repair technician inspect your brakes annually, twice a year if you do heavy hauling and towing on a regular basis. Your brake repair technician should check all metal to metal contact points for proper lubrication, which maintains an effective barrier between the different contact points, and inspect brake fluid for metal flake or moisture contamination.
