Detailed Product Description
The DuraGo BR900900-01 disc brake rotor features a full cast iron construction that balances durability with effective heat dissipation. Its vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking and helping to maintain consistent performance under demanding conditions. The rotor is coated with a rust resistant layer to minimize corrosion, which is especially beneficial for vehicles exposed to moisture and road salt.
With a nominal thickness of 0.91 inches (23 mm) and a discard thickness of 0.85 inches (21.5 mm), this rotor meets OEM specifications for thickness and wear limits. The overall diameter of 12.4 inches (315 mm) and 5 mounting bolt holes with a 4.72 inch (120 mm) bolt circle diameter ensure proper fitment on compatible vehicles. The non-directional brake surface allows for flexible installation without concern for rotor orientation.
Compatible Vehicles and Applications
This rotor is compatible with a range of Buick, Cadillac, Chevrolet, and Saab models, including the Buick Allure, LaCrosse, Regal, and Malibu; Cadillac CT5, CT6, and XTS; Chevrolet Camaro and Impala; and Saab 9-5. The DuraGo BR900900-01 is designed to meet the braking demands of these vehicles, providing reliable stopping power and rotor longevity.
Common Issues Addressed by This Rotor
- Brake rotor warping or uneven wear causing vibration during braking
- Corrosion and rust buildup reducing rotor lifespan
- Reduced braking efficiency due to overheating or brake fade
- Excessive rotor thickness wear beyond discard limits
- Compatibility issues with OEM mounting specifications
Installation Notes and Tips
Ensure the rotor surface is clean and free of debris before installation. Verify the rotor thickness is within discard limits before mounting. Use proper torque specifications for the 5 mounting bolts to avoid rotor distortion. Since this rotor is non-directional, it can be installed on either side without concern for orientation. ABS tone ring is not included, so verify ABS sensor compatibility separately.
