About the Raybestos Element3; Coated Rotor Line

The Element3; Coated Rotor line by Raybestos focuses on providing rotors with a protective coating that helps resist corrosion and extends rotor life. This coating is particularly beneficial for vehicles exposed to harsh weather conditions or road salt. The 580371FZN rotor combines this coating with a vented design to maintain braking efficiency and rotor integrity over time.

Technical Details and Specifications

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 1.270 inches (32.25 mm), with a discard thickness of 1.209 inches (30.7 mm), indicating when the rotor should be replaced to maintain safe braking performance. The overall diameter measures 11.694 inches (297.05 mm), and the rotor includes 6 mounting bolt holes arranged on a 4.528-inch (115 mm) bolt circle diameter, ensuring compatibility with the specified vehicle models. The overall height of 2.051 inches (52.1 mm) supports proper fitment and brake system clearance.

Compatible Vehicles and Applications

• Buick Montana
• Chevrolet Relay
• Pontiac Terraza
• Saturn Uplander

This rotor is designed specifically for these models, providing a direct replacement that meets factory specifications.

Common Issues Addressed by This Rotor

• Brake rotor warping due to heat buildup
• Corrosion and rust on rotor surfaces
• Reduced braking efficiency from worn or thin rotors
• Brake noise caused by uneven rotor wear
• Vibration or pulsation during braking

Installation Notes and Tips

Ensure the rotor is installed on vehicles with 6 lug/stud holes and a 115 mm bolt circle diameter. Verify the rotor thickness before installation and replace if below the discard thickness of 1.209 inches (30.7 mm). Clean the rotor surface to remove any protective coating residue before mounting brake pads. Proper torque specifications should be followed for mounting bolts to avoid rotor distortion.

Quality Assurance and Warranty

Raybestos rotors undergo rigorous quality control to meet OEM standards. The Element3; Coated Rotor line includes corrosion-resistant coatings to extend rotor life. Warranty coverage details should be confirmed with the manufacturer or distributor, as they may vary by region and application.
