Durable Construction and Precise Specifications

The DuraGo BR34123 rotor features a full cast iron construction, providing a solid and reliable braking surface. Its vented design allows air to flow between the rotor faces, reducing heat buildup and minimizing brake fade during extended use. With a nominal thickness of 1.1 inches (28 mm) and a discard thickness of 1.02 inches (26 mm), this rotor maintains optimal performance throughout its service life. The rotor's outside diameter of 12.01 inches (305 mm) and five mounting bolt holes with a 4.75 inch (120.7 mm) bolt circle diameter ensure a precise fit for the specified Jaguar models.

Compatible Jaguar Models and Part Number Details

This disc brake rotor is specifically designed for Jaguar vehicles including the Vanden Plas, XJ8, XJR, and XK8. The part number BR34123 identifies this exact rotor, ensuring compatibility and ease of ordering. It is a conventional, non-directional rotor without cross-drilling or slotting, suitable for standard braking systems without ABS tone rings.

Common Issues Addressed by This Rotor

• Brake rotor warping causing vibration during braking
• Reduced braking efficiency due to worn or thin rotors
• Overheating and brake fade from insufficient heat dissipation
• Uneven brake pad wear linked to rotor surface irregularities
• Noise or pulsation during braking from damaged rotors

Installation Notes and Tips

When installing the DuraGo BR34123 rotor, ensure the mounting surface is clean and free of rust or debris. Verify the rotor thickness is above the discard limit of 1.02 inches (26 mm) before installation. Use proper torque specifications for the five mounting bolts to avoid rotor distortion. Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s ABS system. It is recommended to replace brake pads simultaneously to maintain optimal braking performance.
