Raybestos R-Line Product Line Details

The R-Line by Raybestos focuses on delivering dependable braking components that meet or exceed OEM specifications. This product line emphasizes durability and consistent performance, making it suitable for drivers who require reliable replacement parts for their vehicles. The 582037R rotor benefits from this approach, providing a vented design that helps maintain optimal operating temperatures and reduces brake fade.

Technical Specifications and Features

This disc brake rotor features a vented design to enhance heat dissipation during braking, which is critical for maintaining braking efficiency and rotor longevity. The nominal thickness of 1.181 inches (30.000 mm) ensures structural integrity, while the discard thickness of 1.063 inches (27.000 mm) indicates the minimum safe thickness before replacement is necessary. The rotor’s outside diameter of 12.638 inches (321.000 mm) and inside diameter of 7.500 inches (190.500 mm) are designed to fit precisely on the specified Buick and Cadillac models. The rotor includes five mounting bolt holes with a diameter of 0.559 inches (14.200 mm) arranged on a 4.528 inch (115.000 mm) bolt circle diameter, ensuring secure installation. The smooth surface type promotes even brake pad wear and consistent braking feel.

Applications and Problem Solving

• Replacement for worn or warped rotors on Buick Cascada and Cadillac ELR
• Addresses brake fade caused by overheating through vented rotor design
• Resolves uneven brake pad wear due to rotor surface irregularities
• Eliminates vibrations or pulsations during braking from rotor thickness variations
• Restores braking performance compromised by rotor warping or damage

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 1.063 inches (27.000 mm) before installation. Clean the rotor surface to remove any protective coatings or debris for optimal pad contact. Verify the mounting bolt hole pattern matches the vehicle’s hub assembly, specifically five bolts on a 4.528 inch (115.000 mm) circle. Use proper torque specifications when securing the rotor to avoid warping. It is recommended to replace brake pads simultaneously to maintain balanced braking performance.

Quality Assurance and Warranty

Raybestos R-Line rotors are manufactured to meet OEM standards, ensuring consistent quality and fitment for Buick Cascada and Cadillac ELR vehicles. The vented rotor design supports durability under normal driving conditions. While specific warranty details are not provided here, Raybestos products typically come with a limited warranty against defects in materials and workmanship.
