Detailed Product Description

The DuraGo BR900940 disc brake rotor is constructed from full cast iron, providing a balance of strength and thermal conductivity essential for effective braking. Its vented design allows air to circulate between the rotor surfaces, helping to dissipate heat and reduce the risk of brake fade during extended use. The drum-in-hat construction integrates a parking brake drum within the rotor, making it compatible with BMW X5 and X6 models that require this feature. This rotor does not include an ABS tone ring and features a non-directional braking surface, allowing for flexible installation without concern for rotor orientation.
