Grinding or growling means that your brake pads have completely worn down to the metal. Don't waste time getting your car to a certified brake repair technician, as each of these instances warrants brake repair. There's too much at stake to leave the job to amateurs. After having brake repair work done on your car, you may still hear your brakes squeal when stopping. This usually signifies that the brake repair process wasn't completely finished and may not indicate a problem, but you would be wise to take your car back to the shop anyway.
