Detailed Product Description

This disc brake rotor features a vented design to enhance cooling during braking, reducing the risk of brake fade under demanding conditions. The full cast construction provides strength and resistance to warping. With a nominal thickness of 0.783 inches and a discard thickness of 0.709 inches, this rotor maintains safe operational limits for extended service life. The smooth surface finish ensures consistent contact with brake pads, contributing to stable braking performance. The rotor’s dimensions, including a 12.787-inch outside diameter and 8.457-inch inside diameter, are tailored for the Jaguar XJ, ensuring proper fitment and function.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Jaguar XJ models
• Addresses brake pulsation caused by uneven rotor surfaces
• Improves heat dissipation to reduce brake fade during heavy use
• Restores braking efficiency compromised by rotor thickness below discard limits
• Suitable for conventional braking systems without ABS tone ring requirements

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it exceeds the discard thickness of 0.709 inches. Clean the rotor surface to remove any protective coatings or debris before mounting. Verify the 5-lug bolt pattern and mounting bolt hole circle diameter of 108 mm for compatibility with the Jaguar XJ hub assembly. This rotor does not include bearings or an ABS tone ring, so confirm these components are present or replaced as needed during installation.

Quality Assurance

Raybestos R-Line rotors are manufactured to meet or exceed OEM standards for fit, form, and function. The full cast vented design undergoes rigorous quality control to ensure durability and consistent braking performance. While specific warranty details are not provided, Raybestos products typically adhere to industry quality benchmarks for automotive brake components.
