When it comes to the safety of your vehicle, properly maintaining the brake system is one of the most important measures you can take. A grinding noise coming from the car's rear wheels when you slow down is a sign that your brakes are dangerously worn down and must be serviced immediately.


When you press the brake pedal in your car, the front and rear brakes are engaged to slow down the wheels. A grinding or scraping noise occurs when the brake linings have been worn down to the point where metal is exposed and is rubbing against the brake disc or drum.


Take your vehicle to a reputable repair shop as soon as possible to have the brake linings replaced. If you've been living with the grinding sound for some time, you may have severely damaged the brake rotor. If this is the case, the rotor also will have to be replaced and the cost of the job will go up quickly.


The price of brake repair varies depending on car make and model, but the average cost of a brake inspection and lining replacement is between $90 and $250 per axle. If your rotors need replacement as well, the cost can rise to between $300 and $650. If you are a AAA member, going to a shop that offers a AAA discount can help you save some money.
