The Brembo PISTA two-piece replacement disc, 380 x 34 mm with 65a 17 mm airgap, T3 72V right-hand (RH) orientation, is a direct-fit hat-and-ring rotor sized to these specifications. Replace the matching right-side disc as part of axle service; pairing left and right components preserves correct airgap and rotor geometry for even braking contact.
