Check engine light A basic primer
An occasional noise is to be expected from time to time of course, but when it happens on a regular basis, you may have to bring your car in to have an expert perform brake repair. 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. A loud squeal every time you brake on the other hand may be an indication that your brake's linings have become hard and crystallized, and are therefore not functioning as well as they should be.
