Detailed Product Description

This Raybestos disc brake rotor is part of the Specialty - Street Performance; Coated Rotor line, designed to meet the demands of street-driven vehicles requiring dependable braking under varied conditions. The vented rotor construction enhances airflow to reduce heat buildup during braking, which helps maintain performance and reduces the risk of brake fade. The coated finish provides a protective layer against rust and corrosion, which is especially beneficial for vehicles exposed to moisture and road salts.

With a nominal thickness of 0.906 inches (23.000 mm) and a discard thickness of 0.827 inches (21.000 mm), this rotor maintains structural integrity and safety throughout its service life. The 12.398 inch (314.900 mm) outside diameter and 8.150 inch (207.000 mm) inside diameter ensure proper fitment and compatibility with the braking system of Buick ELR, Regal Sportback, and Regal TourX models. The rotor features five mounting bolt holes and a smooth braking surface to provide consistent pad contact and braking efficiency.

Applications and Problem Solving

• Replacement for worn or warped rotors on Buick ELR, Regal Sportback, and Regal TourX
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Improves heat dissipation to reduce brake fade during extended use
• Prevents corrosion-related rotor damage with coated surface
• Restores braking performance for vehicles with reduced stopping power

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (0.827 inches) before installation
• Clean mounting surface and hub to prevent rotor runout
• Torque mounting bolts to manufacturer specifications for secure fitment
• Inspect brake pads and replace if worn to ensure optimal rotor performance
• Perform a bed-in procedure after installation to maximize braking efficiency
