About the Hella Pagid - High Carbon and Fully Coated Product Line

This rotor is part of the Hella Pagid - High Carbon and Fully Coated line, which focuses on enhanced durability and corrosion resistance. The fully coated surfaces help protect against rust and extend the rotor's service life, while the high carbon content in the cast iron improves wear resistance and heat management. This combination is ideal for vehicles like the Chevrolet Trailblazer and GMC Envoy that require reliable braking under varied conditions.

Detailed Product Description

The Pagid 355122312 disc brake rotor is constructed from gray cast iron, a material known for its excellent thermal conductivity and strength. The vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking and minimizing the risk of brake fade. Both the disc and hat surfaces are coated to resist rust and corrosion, which is critical for maintaining performance and longevity, especially in regions with harsh weather conditions. With an outside diameter of 325 mm and a height of 85.20 mm, this rotor is designed to fit specific models such as the Buick Rainier, Chevrolet SSR, and Saab 9-7x. The full cast construction ensures the rotor maintains its shape and structural integrity under stress, while the 8 bolt holes provide a secure and precise fit.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake vibration
• Upgrading corroded rotors to improve braking reliability
• Addressing brake fade due to overheating in vented rotor applications
• Restoring proper rotor thickness to meet manufacturer specifications
• Improving rust resistance in vehicles exposed to moisture and road salt

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the rotor thickness is above the discard thickness of 18.50 mm to maintain safety and performance. Use the correct torque specifications for the 8 bolt holes to avoid warping. It is recommended to replace brake pads simultaneously to ensure even wear and optimal braking efficiency. Check compatibility with your specific vehicle model, such as the GMC Envoy XL or Oldsmobile Bravada, before installation.
