Detailed Product Description

The DuraGo BR900506 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. This rotor is designed with a drum-in-hat configuration, allowing it to function with rear drum parking brakes commonly found on Cadillac and Chevrolet Camaro and CTS models. The non-directional brake surface simplifies installation by allowing the rotor to be mounted in either orientation without affecting performance.

Installation Notes and Tips

When installing the DuraGo BR900506 rotor, ensure the mounting surface is clean and free of rust or debris.
