Brake drums are cylindrical shaped components in a vehicle braking system which is usually made of cast iron. The brake drum rotates with the wheel and when driver applies brake the lining pushes against the brake drums and the ensuing friction slows or stops the car. It absorbs and discharges the heat generated during braking. Our Automotive Parts online store has wide range of Brake Drums in Genuine and after market brands.
