Detailed Product Description

The DuraGo BR34094 is a vented disc brake rotor constructed from cast iron, providing a balance of durability and heat management. Its full cast design enhances strength and longevity, making it suitable for the braking demands of Jaguar vehicles such as the Vanden Plas, XJ8, XJ12, XJR, and XJS. The rotor features a drum-in-hat configuration, integrating a drum brake surface within the rotor hat area, which is common in certain Jaguar brake systems. With a 5-bolt mounting pattern and a 12.01-inch outside diameter, this rotor is engineered to meet OEM specifications for precise fitment and reliable braking performance. The non-directional brake surface allows for flexible installation without concern for rotor orientation. Although it does not include an ABS tone ring or rust-resistant coating, the rotor’s cast iron material ensures consistent braking under normal operating conditions.

Compatible Vehicles and Applications

• Jaguar Vanden Plas
• Jaguar XJ6
• Jaguar XJ8
• Jaguar XJ12
• Jaguar XJR
• Jaguar XJS
• Jaguar XK8

Common Issues Addressed by This Rotor

• Brake pulsation caused by warped rotors
• Reduced braking efficiency due to worn rotor thickness
• Overheating from insufficient heat dissipation
• Uneven brake pad wear linked to rotor surface condition
• Noise and vibration during braking from damaged rotors

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (0.73 inches) before installation
• Clean mounting surface to prevent rotor runout
• Torque mounting bolts to manufacturer specifications for secure fitment
• Check compatibility with drum-in-hat brake systems on Jaguar models
• Inspect brake pads and replace if worn to maintain optimal braking

Quality Assurance and Warranty

DuraGo disc brake rotors are manufactured to meet or exceed OEM standards for fit, form, and function.
