Technical Details and Construction

The DuraGo BR31392 rotor is constructed from full cast iron, providing a solid and durable braking surface. Its vented design allows air to flow between the rotor faces, helping to dissipate heat generated during braking and reducing the risk of brake fade. The rotor measures 12.56 inches in outside diameter and has a nominal thickness of 1.1 inches, with a discard thickness of 1.02 inches, indicating when replacement is necessary. The rotor features five mounting bolt holes spaced on a 4.5-inch bolt circle diameter, ensuring proper fitment on compatible vehicles.

Compatible Vehicles and Applications

This disc brake rotor is compatible with various Lexus and Toyota models, including the Lexus RX330, RX350, RX400h, and the Toyota Highlander. It is designed to meet the braking demands of these vehicles, providing consistent performance under normal driving conditions.

• Addresses brake rotor wear and thickness below discard limits
• Resolves issues with brake noise caused by warped rotors
• Improves heat dissipation to reduce brake fade during extended use
• Restores proper rotor dimensions for safe and effective braking

Installation Notes and Tips

When installing the DuraGo BR31392 rotor, ensure the rotor surface is clean and free of any contaminants before mounting. Since this rotor does not include an ABS tone ring, verify compatibility with your vehicle’s ABS system. Use proper torque specifications for the five mounting bolts to secure the rotor firmly. It is recommended to replace brake pads simultaneously to maintain optimal braking performance.
