Raybestos Specialty - Truck Product Line Details

The Specialty - Truck line from Raybestos focuses on heavy-duty brake components tailored for truck applications. This product line emphasizes durability and precise engineering to handle the demands of larger vehicles such as the Nissan TITAN and Armada series. The 980198 rotor exemplifies this with its vented design and drum-in-hat configuration, providing effective heat dissipation and compatibility with integrated parking brake systems.

Technical Description and Specifications

This disc brake rotor features a vented design that improves heat dissipation during braking, reducing the risk of brake fade under heavy loads. The drum-in-hat type rotor integrates a parking brake drum within the rotor assembly, which is common in truck brake systems. With an outside diameter of 12.580 inches and a nominal thickness of 0.550 inches, the rotor maintains structural integrity while meeting OEM specifications. The discard thickness of 0.472 inches indicates the minimum allowable thickness before replacement is necessary, ensuring safety and performance. The rotor mounts with six bolts on a 5.500 inch bolt circle diameter, matching the factory mounting pattern for the specified Nissan and INFINITI models.

Compatible Vehicles and Common Applications

• Nissan Armada and Pathfinder Armada requiring vented disc brake rotors
• INFINITI QX56 brake system replacement
• Nissan TITAN models with drum-in-hat rear brake rotors
• Replacement for worn or damaged rear disc brake rotors on compatible trucks
• Addressing brake noise, vibration, or reduced braking efficiency

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it exceeds the discard thickness of 0.472 inches. Proper cleaning of the rotor surface and hub mounting area is recommended to prevent uneven braking or noise. Verify the six mounting bolt holes align correctly with the vehicle’s hub assembly. Since this rotor includes a drum-in-hat design, confirm compatibility with the parking brake shoes and hardware. Follow manufacturer torque specifications for mounting bolts to maintain safety and performance.
