Detailed Product Features and Construction

This disc brake rotor is made from gray cast iron, a material known for its strength and ability to withstand high temperatures generated during braking. The rotor features a vented design, which allows air to flow between the rotor surfaces, enhancing heat dissipation and reducing the risk of brake fade. Both the disc and hat surfaces are fully coated, providing a rust-resistant barrier that extends the rotor's service life, especially in environments prone to moisture and corrosion.

The rotor's full cast construction ensures structural integrity and consistent performance under demanding conditions. With a nominal thickness of 28.00 mm and a discard thickness of 26.40 mm, this rotor maintains safety standards throughout its usable life. The 7 bolt hole configuration and 302.00 mm outside diameter are specifically designed to match the brake system requirements of compatible BMW models.

Hella Pagid - High Carbon and Fully Coated Product Line

The Hella Pagid - High Carbon and Fully Coated line focuses on rotors that combine high carbon content with a protective coating to improve thermal stability and corrosion resistance. This product line is tailored to provide consistent braking performance and durability, making it suitable for BMW vehicles requiring reliable OEM-quality replacement parts. The fully coated finish on both the disc and hat surfaces helps prevent rust, which is critical for maintaining rotor integrity over time.

Compatible BMW Models and Applications

• BMW 540i
• BMW 735i and 735iL
• BMW 740i and 740iL
• BMW 750iL

This rotor is designed specifically for these BMW models, ensuring proper fitment and optimal braking performance when replacing worn or damaged rotors.

Common Issues Addressed by This Rotor

• Brake rotor warping due to heat stress
• Corrosion and rust buildup on rotor surfaces
• Reduced braking efficiency from worn or thin rotors
• Brake noise caused by uneven rotor wear
• Overheating and brake fade during extended use

Installation Notes and Tips

When installing the Pagid disc brake rotor 355122072, ensure the rotor surface is clean and free of any protective coatings or debris before mounting. Verify the rotor thickness is above the discard limit of 26.40 mm to maintain safety. Use the correct torque specifications for the 7 bolt holes to avoid rotor distortion. It is recommended to replace brake pads simultaneously to ensure even wear and optimal braking performance.
