The rotor’s nominal thickness of 0.435 inches (11.050 mm) ensures durability, while the discard thickness of 0.354 inches (9.000 mm) indicates the minimum safe thickness for replacement. The 5-bolt mounting pattern with a 115.000 mm bolt circle diameter and a center hole diameter of 2.782 inches (70.650 mm) ensures precise fitment on compatible vehicles.

Element3; Coated Rotor Product Line Features

The Element3; Coated Rotor line from Raybestos features a protective coating designed to resist rust and corrosion, extending the rotor’s service life and maintaining a cleaner appearance. This coating also helps reduce brake noise and vibration, contributing to a smoother braking experience. The vented design enhances thermal management, which is critical for maintaining consistent braking performance on vehicles such as the Buick Aztek and Pontiac Montana.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing rotor corrosion and surface rust on older vehicles
• Improving heat dissipation to reduce brake fade during heavy use
• Restoring proper parking brake function with integrated drum-in-hat design
• Ensuring correct fitment for rear disc brake systems on Buick, Oldsmobile, and Pontiac models

Installation Notes and Tips

• Verify rotor thickness before installation; replace if below discard thickness of 0.354 inches
• Ensure mounting surfaces and bolt holes are clean and free of debris
• Torque mounting bolts to manufacturer specifications to avoid rotor warping
• Inspect brake pads and hardware for wear during rotor replacement
• Check parking brake adjustment after installation due to drum-in-hat design
