- Vented and cross-drilled design to improve cooling and reduce brake fade
- Drum-in-hat construction with integrated parking brake drum
- Outside diameter of 12.01 inches (305 mm) and nominal thickness of 1.02 inches (26 mm)
- Five mounting bolt holes with a 4.53 inch (115 mm) bolt circle diameter
- Non-directional brake surface for versatile installation
Detailed Product Features and Specifications
The DuraGo BR900500 rotor is constructed from full cast iron, providing a solid and reliable 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 warping. The cross-drilled holes further enhance cooling and help evacuate gases and debris from the brake pad surface. This rotor features a drum-in-hat design, integrating a parking brake drum for vehicles equipped with rear drum parking brakes. With an overall height of 2 inches (50.7 mm) and a center hole diameter of 2.78 inches (70.6 mm), it is specifically designed to fit the brake system of the Pontiac Grand Prix. The rotor does not include an ABS tone ring and has a non-directional braking surface, allowing for flexible installation without concern for rotor orientation.
Compatible Vehicles and Applications
This disc brake rotor is compatible with the Pontiac Grand Prix, ensuring proper fitment and performance. It is suitable for drivers seeking replacement rotors that meet original equipment specifications for braking efficiency and durability.
- Replacement for worn or warped rotors on Pontiac Grand Prix

Installation Notes and Tips
When installing the DuraGo BR900500 rotor, ensure the mounting surface is clean and free of rust or debris to promote proper rotor seating. Use the correct torque specifications for the five mounting bolts to avoid rotor distortion. Since this rotor is non-directional, it can be installed on either side of the vehicle without concern for orientation. Verify that the rotor thickness meets or exceeds the discard thickness of 0.94 inches (24 mm) before installation to maintain safe braking performance.
