My little discussion forum on radiator service
Your brake wear indicators could be scraping against your rotors if your brakes squeal when you release your brake pedal; however, the grinding and growling sound of metal on metal means that your brake pads have completely worn down. Regardless of the signals your brakes send, take your car in for brake repair as soon as possible. You aren't doing yourself any favors by putting it off. The longer you drive with bad brakes, the greater the danger to you and your passengers. Experts recommend that you have your brakes inspected at least once a year, even if they appear to be working just fine.
