Detailed Product Description

The DuraGo BR31240 disc brake rotor is constructed from full cast iron, providing a solid and durable braking surface. Its vented design enhances airflow to reduce heat buildup during braking, which helps maintain consistent stopping power and reduces the risk of rotor warping. With an outside diameter of 10.87 inches and a nominal thickness of 1.07 inches, this rotor is engineered to meet the exact fitment requirements for Mitsubishi Montero vehicles. The rotor features six mounting bolt holes with a 4.25 inch bolt circle diameter, ensuring secure attachment to the wheel hub. The non-directional brake surface allows for flexible installation without concern for rotor orientation.

Compatible Vehicles and Applications

This disc brake rotor is compatible with Mitsubishi Montero models requiring part number BR31240. It is designed to replace worn or damaged rotors and restore proper braking function.

• Eliminates brake pulsation caused by warped rotors
• Resolves excessive brake noise due to uneven rotor surfaces
• Restores braking efficiency lost from rotor wear below discard thickness
• Prevents brake fade by improving heat dissipation with vented design
• Addresses rotor thickness variation affecting brake pad contact

Installation Notes and Tips

When installing the DuraGo BR31240 rotor, ensure the mounting surface is clean and free of rust or debris. Verify the rotor thickness is above the discard thickness of 1 inch before installation. Use proper torque specifications for the six mounting bolts to avoid rotor distortion. Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s ABS system. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.
