The grinding or growling of metal on metal means, of course, that the pads are completely worn away. Experts strongly recommend that you have your brakes checked as soon as you sense that something is amiss. To be on the safe side, brakes should also be inspected on a yearly basis even if nothing appears to be wrong. Certain maintenance tasks should be performed regularly as well in order to keep your brakes in optimal condition and brake repair to a minimum. Be sure to have your brake fluid tested for the presence of metal particles and moisture.
