The Brembo PISTA two-piece replacement disc, 380 x 34 mm with 65a 20 mm airgap, T3 72V right-hand (RH) orientation, is a direct-fit hat-and-ring rotor specified for this diameter, thickness and airgap. Replace the right-side disc as part of axle service and pair it with the matching left-side piece to preserve proper airgap and even braking contact.
