Detailed Product Description

The DuraGo BR31040 disc brake rotor is engineered with full cast construction using high-quality cast iron, providing a solid and durable braking surface. Its vented design enhances heat dissipation during braking, reducing the risk of brake fade under normal driving conditions. The rotor features a drum-in-hat design, which integrates the parking brake drum into the rotor itself, making it compatible with vehicles equipped with drum parking brakes like the Lexus LS400. This rotor does not include an ABS tone ring and has a non-directional braking surface, allowing for flexible installation without concern for rotor orientation.
