Hella Pagid - High Carbon and Fully Coated Product Line

This rotor is part of the Hella Pagid - High Carbon and Fully Coated line, which emphasizes enhanced durability and corrosion protection. The fully coated surfaces help prevent rust buildup, extending the rotor's service life, while the high carbon content in the gray cast iron improves thermal stability and wear resistance. This combination supports consistent braking performance for BMW vehicles like the 330Ci, 330i, 330xi, and Z4.

Detailed Product Description

The Pagid disc brake rotor 355121992 is constructed from gray cast iron, a material known for its excellent heat dissipation and mechanical strength. Its vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking and minimizing the risk of brake fade. The rotor’s nominal thickness of 25.00 mm ensures a solid braking surface, while the discard thickness of 23.40 mm indicates when replacement is necessary to maintain safety. Both the disc and hat are coated to resist rust and corrosion, which is critical for maintaining rotor integrity over time. The full cast construction provides a robust and reliable component that meets the demands of BMW braking systems. With six bolt holes and a 325 mm outside diameter, this rotor is engineered for precise fitment on compatible BMW models.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on BMW 330Ci, 330i, 330xi, and Z4
• Addresses brake noise and vibration issues caused by uneven rotor surfaces
• Improves braking consistency by reducing heat-related fade
• Prevents rust and corrosion that can compromise rotor performance
• Restores proper rotor thickness for safe braking operation

Installation Notes and Tips

• Ensure rotor discard thickness is checked before installation
