Hella Pagid OE Two Piece Design Features

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. The two-piece construction features a high carbon friction ring paired with an aluminum hat, which reduces unsprung weight and improves thermal management. The fully coated surfaces provide enhanced corrosion resistance, extending the rotor's service life under demanding conditions.

Technical Description and Compatibility

The composite vented design of this disc brake rotor allows for efficient heat dissipation, reducing the risk of brake fade during extended use. The gray cast iron friction ring offers consistent braking performance, while the aluminum hat contributes to weight reduction and improved vehicle handling. The rotor’s dimensions, including a 348 mm outside diameter and 66.10 mm height, are tailored for precise fitment on various BMW models such as the 535i GT, 550i xDrive, 650i Gran Coupe, and 740Li xDrive. The 6-bolt hole configuration ensures secure mounting and compatibility with the specified vehicles.

Applications and Problem Solving

• Replacement for worn or warped rotors on compatible BMW models
• Addresses brake noise and vibration issues caused by uneven rotor surfaces
• Improves braking consistency and heat management during heavy use
• Prevents rust and corrosion with fully coated surfaces
• Supports optimal brake pad contact for enhanced stopping power

Installation Notes and Tips

Ensure the rotor is installed on compatible BMW models listed in the fitment section. Verify the rotor thickness before installation; replace if below the discard thickness of 34.40 mm. Properly torque the 6 bolts to manufacturer specifications to avoid rotor warping. It is recommended to replace brake pads simultaneously to maintain optimal braking performance.

Quality Assurance and Warranty

Pagid rotors are manufactured to meet OE standards, with quality controls in place to ensure durability and performance. The rust-resistant coating protects against environmental damage, contributing to longer service life. Warranty details should be confirmed with the point of purchase or manufacturer documentation.
