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 surface and high carbon content in the gray cast iron material help reduce rust and extend rotor life, making it suitable for BMW 525i, 528i, and 530i vehicles that require dependable braking components.

Detailed Product Description

The Pagid 355122642 disc brake rotor is constructed from gray cast iron, a material known for its excellent thermal conductivity and wear resistance. The vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking and helping to maintain consistent performance. Both the disc and hat are coated to protect against rust and corrosion, which is critical for maintaining rotor integrity over time. With a nominal thickness of 20.00 mm and a discard thickness of 18.40 mm, this rotor provides a balance between longevity and safety. The 6 bolt hole configuration ensures proper alignment and fitment on compatible BMW models.

Compatible Vehicles and Common Applications

• Replacement rotor for BMW 525i brake system maintenance
• Suitable for BMW 528i requiring vented disc brake rotors
• Used in BMW 530i for restoring braking efficiency
• Addresses issues such as rotor warping and uneven wear
• Helps resolve brake noise caused by surface corrosion

Installation Notes and Tips

When installing the Pagid 355122642 rotor, ensure the vehicle is securely lifted and the wheel hub is clean and free of debris. Verify the rotor thickness before installation to confirm it is above the discard limit of 18.40 mm. Proper torque specifications should be followed for the 6 bolt holes to avoid rotor distortion. It is recommended to replace brake pads simultaneously to ensure optimal braking performance and rotor longevity.
