Technical Description and Specifications

This disc brake rotor features a vented design that enhances cooling by allowing air to flow between the rotor surfaces, reducing the risk of brake fade during extended use. The rotor’s nominal thickness of 1.181 inches (30.000 mm) ensures sufficient material for longevity, while the discard thickness of 1.063 inches (27.000 mm) indicates the minimum safe thickness before replacement is necessary. The smooth surface finish promotes even brake pad wear and consistent stopping power. With five mounting bolt holes arranged on a 2.654-inch (67.400 mm) bolt circle diameter, this rotor is compatible with specific models including the Buick Caprice, Cadillac CTS and XTS, Chevrolet Corvette, and Regal.

Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing reduced braking efficiency due to rotor thickness below discard limits
• Improving heat dissipation to prevent brake fade on heavy or frequent braking
• Restoring smooth braking performance by replacing rotors with surface irregularities
• Ensuring proper fitment on Buick, Cadillac, and Chevrolet vehicles requiring a 5-bolt vented rotor

Installation Notes and Tips

• Verify rotor dimensions and bolt pattern compatibility with your vehicle before installation
• Inspect brake pads and hardware for wear and replace as necessary during rotor installation
• Clean rotor surface with brake cleaner to remove any protective coating before mounting
• Torque mounting bolts to manufacturer specifications to ensure secure fitment
• Perform a bed-in procedure after installation to optimize braking performance and rotor life
