Raybestos R-Line Product Line Details

The R-Line by Raybestos focuses on delivering dependable replacement brake components that meet or exceed OEM specifications. This product line emphasizes durability and consistent performance, making the 680507R rotor suitable for heavy-duty applications found in full-size SUVs like the Ford Expedition and Lincoln Navigator.

Technical Specifications and Features

The 680507R rotor features a vented design that improves heat dissipation during braking, reducing the risk of brake fade under demanding conditions. The drum-in-hat configuration integrates a parking brake drum within the rotor, eliminating the need for a separate drum and simplifying installation. With six mounting bolt holes arranged on a 135 mm bolt circle diameter, this rotor ensures secure fitment. The nominal thickness of 0.866 inches (22 mm) provides a solid braking surface, while the discard thickness of 0.787 inches (20 mm) indicates the minimum safe thickness for replacement.

Applications and Problem Solving

• Replacement for worn or warped rotors on Ford Expedition and Lincoln Navigator
• Addresses brake noise and vibration issues caused by uneven rotor surfaces
• Improves braking performance and heat management in heavy-duty driving conditions
• Restores proper parking brake function with integrated drum-in-hat design
• Prevents premature rotor failure due to thickness wear beyond discard limits

Installation Notes and Tips

Ensure the rotor mounting surface and hub are clean and free of debris before installation. Verify the rotor thickness is above the discard thickness of 0.787 inches (20 mm) before reuse. Use proper torque specifications for the six mounting bolts on the 135 mm bolt circle diameter to secure the rotor. The drum-in-hat design requires compatible parking brake shoes; confirm compatibility during installation.

Quality Assurance and Warranty

Raybestos R-Line rotors are manufactured to meet OEM standards for fit, form, and function. The 680507R rotor undergoes rigorous quality control to ensure consistent performance and durability. Warranty coverage details should be confirmed with the point of purchase or Raybestos directly.
