Detailed Product Description

The DuraGo BR31073 is a conventional, vented disc brake rotor specifically designed for Pontiac LeMans vehicles. Constructed from full cast iron, it offers a balance of durability and thermal management. The vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking and helping to prevent brake fade. With a nominal thickness of 0.95 inches and a discard thickness of 0.83 inches, this rotor provides a clear service life indicator to ensure safe replacement timing. The rotor features six mounting bolt holes with a 100 mm bolt circle diameter, making it compatible with the factory specifications of the Pontiac LeMans. Its non-directional brake surface allows for flexible installation without concern for rotor orientation.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing reduced braking efficiency due to rotor thinning
• Eliminating noise and vibration from uneven rotor surfaces
• Restoring proper rotor dimensions for safe brake pad contact
• Upgrading to a vented rotor for improved heat dissipation

Installation Notes and Tips

When installing the DuraGo BR31073 rotor on a Pontiac LeMans, ensure the mounting surface is clean and free of rust or debris. Verify the rotor thickness before installation to confirm it meets the minimum discard thickness. Use proper torque specifications for the six mounting bolts to avoid rotor warping. Since this rotor is non-directional, it can be installed on either side without concern for directional rotation. It is recommended to replace brake pads simultaneously to ensure even wear and optimal braking performance.
