Detailed Product Description

The DuraGo BR900312 disc brake rotor is constructed from full cast iron, providing a balance of durability and effective heat management. Its vented design allows air to circulate between the rotor surfaces, helping to dissipate heat generated during braking and reducing the risk of brake fade under heavy use. With a nominal thickness of 1.18 inches and a discard thickness of 1.13 inches, this rotor meets OEM specifications for thickness tolerances, ensuring safe and reliable braking performance.

Measuring 11.93 inches in outside diameter and featuring five mounting bolt holes on a 4.65 inch bolt circle diameter, this rotor is compatible with a range of GM vehicles including the Buick LeSabre, Cadillac DeVille, Chevrolet Monte Carlo, Pontiac Bonneville, and Park Avenue. The non-directional brake surface allows for flexible installation without concern for rotor orientation. This conventional rotor does not include an ABS tone ring and is designed for vehicles that do not require this feature.
