Detailed Product Description

This Power Stop rotor is a vented disc brake rotor designed to provide consistent braking performance and durability. The vented design helps dissipate heat generated during braking, reducing the risk of brake fade and maintaining effective stopping power. The rotor features a Geomet coating, which offers enhanced rust resistance compared to standard rotors, helping to maintain structural integrity and appearance over time.

With a nominal thickness of 0.91 inches (23.00 mm) and a discard thickness of 0.83 inches (21.00 mm), this rotor meets the specifications required for safe and effective braking. The overall height of 1.80 inches (45.30 mm) and an outside diameter of 12.40 inches (315.10 mm) ensure proper fitment and compatibility with the rear brake assemblies of the Buick Envision and Cadillac XT4. The mounting bolt hole circle diameter measures 120.00 mm with 5 lug holes, matching factory specifications for secure installation.
