Detailed Product Description
The DuraGo BR901830 disc brake rotor is constructed from cast iron, providing a robust and heat-resistant braking surface. Its vented design allows air to flow between the rotor surfaces, enhancing heat dissipation during braking and helping to maintain consistent stopping power. With a nominal thickness of 0.91 inches and a discard thickness of 0.83 inches, this rotor meets the specifications required for safe and effective brake performance. The rotor measures 12.4 inches in outside diameter and features five mounting bolt holes arranged on a 120 mm bolt circle diameter, ensuring proper fitment on compatible vehicles.
This rotor is designed as a conventional, non-directional rotor without cross-drilling or slotting, which suits drivers looking for a straightforward replacement part without additional noise or dust concerns. The overall height of 1.77 inches (45 mm) and center hole diameter of 2.66 inches (67.5 mm) align with factory specifications for the Buick Envision and Cadillac XT4 models.
