My little obsession on radiator repair
A brake fluid leak manifests itself by sight (a light amber color) and a smell that is distinctive. Rotor surface issues will cause your brake pedal or wheel to vibrate. 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. The grinding and growling sound of metal on metal means only one thing: that your brake pads are completely worn away.
