About the Raybestos Element3; Coated Rotor Line

The Element3; Coated Rotor line from Raybestos focuses on delivering rotors with a protective coating that helps prevent rust and corrosion, which can degrade braking performance over time. This coating extends the rotor’s service life while maintaining the structural integrity and heat dissipation properties of a vented rotor. The 580839FZN part benefits from this technology, making it suitable for vehicles that require reliable stopping power under various driving conditions.

Technical Specifications and Features

This disc brake rotor features a vented design that enhances airflow to reduce heat buildup during braking, which helps prevent brake fade. The rotor’s nominal thickness is 1.181 inches (30.000 mm), with a discard thickness of 1.063 inches (27.000 mm), indicating when replacement is necessary to maintain safe braking. The rotor has a smooth surface type, ensuring even pad wear and consistent braking feel. It includes five mounting bolt holes with a 120 mm bolt circle diameter and a center hole diameter of 2.654 inches (67.400 mm), matching the factory specifications for the compatible Buick, Chevrolet, and Saab models.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing vibration or noise
• Addressing brake fade due to overheating on vented rotors
• Corrosion resistance to prevent rust buildup on braking surfaces
• Restoring proper rotor thickness for safe braking performance
• Ensuring compatibility with factory mounting bolt patterns for secure installation

Installation Notes and Tips

When installing the Raybestos 580839FZN rotor, ensure the mounting surface is clean and free of debris to promote proper rotor seating. Verify the rotor thickness before installation to confirm it meets the nominal thickness specifications. Use the correct torque settings on the five mounting bolts to avoid rotor warping. It is recommended to replace brake pads simultaneously to ensure optimal braking performance and rotor longevity.

Quality Assurance and Warranty

Raybestos rotors are manufactured to meet or exceed OEM standards for fit, form, and function. The Element3; Coated Rotor line includes a protective coating to enhance durability and corrosion resistance. While specific warranty details for part number 580839FZN should be confirmed with the supplier, Raybestos typically offers limited warranties covering defects in materials and workmanship.
