It works exclusively with WABCO PAN22 calipers on Hendrickson axles, providing the friction surface that brake pads clamp against to slow and stop the vehicle. Rotors are replaced when the disc thickness wears to the minimum discard specification, typically as part of a brake service or pad replacement. This is a high-mileage component engineered for demanding trailer applications.
