Technical Description and Specifications

This disc brake rotor features a vented design with straight vanes that facilitate efficient heat dissipation during braking, reducing the risk of brake fade. The smooth surface finish ensures consistent pad contact and braking performance. The rotor's nominal thickness is 0.787 inches (20.000 mm), with a discard thickness of 0.709 inches (18.000 mm), indicating when replacement is necessary to maintain safety standards. The coated hat and disc surfaces provide additional protection against corrosion, which is critical for vehicles like the Nissan Armada and Infiniti QX56 and QX80 that may encounter harsh driving conditions.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Corrosion damage repair on original equipment rotors
• Improved heat management to reduce brake fade during towing or heavy loads
• Restoring braking performance on Nissan Armada, Infiniti QX56, and QX80 models
• Addressing rotor thickness below manufacturer discard limits

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the rotor thickness with a micrometer to confirm it meets nominal specifications. Use proper torque settings on the 6 lug nuts to avoid rotor warping. Since this rotor does not include bearings or an ABS tone ring, reuse existing components if applicable. The floating disc mounting design requires careful alignment to maintain optimal brake system performance.
