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 high carbon content improves thermal stability and wear resistance, while the full coating on both the disc and hat surfaces protects against rust and environmental damage. This combination supports reliable braking performance over the rotor's lifespan.

Technical Details and Performance

The Pagid 355126321 rotor is constructed from gray cast iron, a material known for its excellent heat absorption and dissipation properties, critical for maintaining braking efficiency. The vented design allows air to circulate between the rotor surfaces, reducing heat buildup and minimizing brake fade during extended use. The coated finish on both the disc and hat surfaces provides a protective barrier against corrosion, which is especially beneficial for Mercedes-Benz GL350, GL450, GLE400, GLS350d, GLS450, and ML400 models that may encounter varied driving environments.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing rotor corrosion and surface rust affecting braking smoothness
• Improving heat dissipation to reduce brake fade during heavy braking
• Ensuring proper rotor thickness to maintain braking efficiency and safety
• Restoring secure rotor fitment with correct bolt hole alignment

Installation Notes and Tips

When installing the Pagid 355126321 rotor, ensure the rotor thickness is above the discard thickness of 29.40 mm to maintain safety standards. Clean the hub surface before mounting to prevent uneven rotor seating. Use the 8 bolt holes to securely fasten the rotor, and verify proper alignment with the vehicle’s specifications. It is recommended to inspect brake pads and related components during rotor replacement for optimal braking system performance.

Quality Assurance and Warranty

Pagid rotors are manufactured to meet strict quality standards, ensuring consistent performance and durability. The rust-resistant coating extends the rotor’s service life by protecting against environmental corrosion.
