Some of the situations that call for brake repair help are described below. Squealing If you often hear a noise from the vicinity of your car's brakes even when you are not braking, the most common cause is worn brake pads. Such an occurrence warrants taking your car in for an immediate inspection of the braking system. If you hear a louder squeal than usual whenever you apply the brakes, your brake linings have probably crystallized, and their function is possibly impaired. This is also a situation that warrants a full brake inspection as early as possible.
