Technical Overview of DuraGo BR900508 Rotor

This DuraGo disc brake rotor features a full cast iron construction that balances strength and thermal conductivity, essential for maintaining braking efficiency under various driving conditions. The vented design allows air to flow between the rotor surfaces, helping to dissipate heat generated during braking and reducing the risk of warping. 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 maintain safe braking performance. The rotor's 13.58-inch diameter and five-bolt mounting pattern ensure compatibility with specific Buick Caprice, Cadillac CTS and XTS, and Chevrolet Regal models. The non-directional braking surface simplifies installation without concern for rotor orientation.
