When the parking brakes are applied, the brake shoes press outward against the inner machined surface of this drum to hold the vehicle in place. You're replacing this part either because the braking surface is worn beyond the maximum wear diameter of 12.37 inches, is cracked, or has been machined too thin to be safe.
