The rotor provides the friction surface that the brake pads clamp against to slow and stop the vehicle, converting kinetic energy into heat. It should be replaced when the thickness wears below the manufacturer’s minimum specification, or if it develops cracks, warpage, or excessive heat checking. This unit is a 430 mm diameter, 45 mm thick rotor with a 10-bolt mounting pattern, commonly used on Hendrickson air disc brake axles.
