About the Hella Pagid OE Two Piece Design

This rotor is part of the Hella Pagid - OE Two Piece Design Made in Europe (Aluminum Hat, High Carbon Friction Ring, Fully Coated) product line. Featuring a two-piece construction with a high carbon friction ring and an aluminum hat, this design reduces unsprung weight and improves heat dissipation. The fully coated surfaces provide corrosion resistance, extending the rotor's service life while maintaining OEM quality standards.

Technical Details and Performance

The disc brake rotor 355120681 combines gray cast iron for the friction surface with an aluminum hat, creating a composite rotor that balances durability and weight savings. The vented rotor design enhances airflow to reduce heat buildup during braking, which helps maintain consistent stopping power and reduces the risk of brake fade. The coated finish on both the disc and hat protects against rust and corrosion, important for longevity in various driving conditions.

Applications and Problem Solving

• Replacement for worn or warped rotors on BMW 550i GT and 7 Series models
• Addresses brake noise and vibration issues caused by uneven rotor surfaces
• Improves heat dissipation to reduce brake fade during heavy use
• Prevents rust and corrosion that can compromise braking efficiency
• Ensures proper fitment and secure mounting with 6 bolt holes

Installation Notes and Tips

When installing the Pagid disc brake rotor 355120681, ensure the rotor is mounted securely using the 6 bolt holes to the hub assembly. Verify that the rotor thickness is above the discard thickness of 34.40 mm before installation. It is recommended to replace brake pads simultaneously to optimize braking performance. Proper cleaning of the rotor surface before installation will help prevent contamination and ensure effective braking.

Quality Assurance and Warranty

Pagid rotors are manufactured to meet or exceed OEM standards, with quality controls in place to ensure consistent performance. The rust-resistant coating and composite construction contribute to the rotor's durability. Warranty coverage details should be confirmed with the point of purchase or manufacturer documentation.
