Technical Details and Construction

The DuraGo BR900510 rotor features a full cast iron construction, providing a solid and durable braking surface. Its vented design helps dissipate heat more effectively than solid rotors, reducing the risk of brake fade during extended use. The rotor’s nominal thickness of 0.91 inches (23 mm) ensures a robust braking surface, while the discard thickness of 0.85 inches (21.5 mm) indicates when replacement is necessary to maintain safe braking performance. This rotor is a drum-in-hat type, integrating a drum brake surface within the rotor hat area, compatible with the rear braking system of the Cadillac CTS.

Compatible Vehicles and Applications

This disc brake rotor is specifically compatible with Cadillac CTS models, ensuring proper fitment and performance. The part number BR900510 corresponds to the exact specifications required for these vehicles, including the 5-bolt mounting pattern and precise dimensions. Using this rotor helps maintain the original braking characteristics of your Cadillac CTS.

• Restores braking efficiency for worn or damaged rotors
• Reduces brake noise and vibration caused by uneven rotor surfaces
• Prevents brake fade by improving heat dissipation
• Addresses rotor thickness below manufacturer specifications
• Ensures proper fitment for Cadillac CTS rear brake assemblies

Installation Notes and Tips

When installing the DuraGo BR900510 rotor, ensure the mounting surface is clean and free of rust or debris. Verify the rotor thickness before installation to confirm it meets nominal specifications. Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s ABS system. Proper torque on mounting bolts is essential to avoid rotor warping. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.
