Detailed Product Description

The Raybestos R-Line 581043R disc brake rotor is a vented rotor designed to provide effective heat dissipation during braking, reducing the risk of brake fade. Its conventional drum-in-hat type construction ensures compatibility with the specified Cadillac ATS and CT4 models. The rotor features a smooth surface type that promotes even brake pad wear and consistent braking performance. With an outside diameter of 11.819 inches and an overall height of 2.402 inches, this rotor meets the precise specifications required for proper fitment and function.

The rotor includes five mounting bolt holes arranged in a 4.520 inch (114.800 mm) bolt circle diameter, with each hole measuring 0.566 inches in diameter. The center hole diameter is 2.787 inches (70.800 mm), ensuring proper alignment on the vehicle hub. The nominal thickness of 1.024 inches allows for a substantial braking surface, while the discard thickness of 0.906 inches indicates when the rotor should be replaced to maintain safety and performance.
