Detailed Product Description

The DuraGo BR34214 is a conventional, full cast disc brake rotor specifically designed for BMW 530i and 540i vehicles. Its cast iron construction offers a balance of durability and effective heat dissipation, essential for maintaining braking efficiency. The rotor features a vented design, which helps reduce heat buildup during braking, minimizing the risk of brake fade. With a nominal thickness of 1.18 inches and a discard thickness of 1.12 inches, this rotor provides a clear service life indicator to ensure timely replacement. The 12.76-inch outside diameter and 5 mounting bolt holes with a 4.72-inch bolt circle diameter ensure proper fitment and secure installation. The non-directional brake surface allows for flexible mounting without concern for rotor orientation.
