Squealing Any noise from your brakes that goes on even when you are not braking is a sign that your brake pads may be worn out. When this happens, you should take your car to a reputable service for a thorough brake system inspection. 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. This is also a situation that warrants a full brake inspection as early as possible. Grinding A deep grinding sound that occurs whether you are driving or hitting the brakes is a more serious condition affecting the brake and possibly the wheel.
