Detailed Product Description

The DuraGo BR900920 disc brake rotor is constructed from full cast iron, providing a solid and durable braking surface suitable for daily driving and moderate performance demands. Its vented design allows air to flow between the rotor faces, reducing heat buildup and helping to maintain braking consistency under load. The rotor measures 10.87 inches (276 mm) in outside diameter and has a nominal thickness of 1.02 inches (26 mm), with a discard thickness of 0.91 inches (23 mm), indicating when replacement is necessary to maintain safe braking performance.

This rotor features five mounting bolt holes with a 4.13 inch (105 mm) bolt circle diameter and a center hole diameter of 2.36 inches (60 mm), ensuring proper fitment on compatible Chevrolet models. The non-directional brake surface allows for flexible installation without concern for rotor orientation. Note that this rotor does not include an ABS tone ring and does not have rust-resistant coating, so regular inspection and maintenance are recommended.
