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 high carbon content improves thermal stability and wear resistance, while the full coating protects against rust and environmental damage, extending the rotor's service life on BMW X3 and X4 vehicles.

Detailed Product Description

The Pagid 355119531 disc brake rotor is constructed from gray cast iron, a material known for its excellent heat dissipation and wear characteristics. With a nominal thickness of 28 mm and a discard thickness of 26.4 mm, this rotor ensures consistent braking performance throughout its lifespan. The vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking. Both the disc and hat surfaces are coated to resist rust, which is critical for maintaining rotor integrity and appearance over time. Mill balancing enhances rotor stability, minimizing vibrations and noise during operation. The rotor features a 5-bolt mounting pattern with a 120 mm bolt circle diameter, compatible with specific BMW X3 and X4 models. Its non-directional smooth surface allows for flexible installation without concern for rotor orientation.

Applications and Problem Solving

• Replacement for worn or warped rotors on BMW X3 and X4
• Addresses brake noise and vibration issues caused by unbalanced rotors
• Prevents rust-related rotor degradation in humid or corrosive environments
• Improves heat dissipation to reduce brake fade during extended use
• Restores braking efficiency and pedal feel for safer driving

Installation Notes and Tips

Installation of the Pagid 355119531 rotor should be performed by qualified personnel to ensure proper fit and function. Verify rotor thickness before installation to confirm it meets minimum specifications. Clean the hub surface and mounting bolts to prevent misalignment. Since this rotor does not include bearings or ABS tone rings, reuse existing components or replace as necessary. Proper torque specifications should be followed for mounting bolts to avoid rotor warping.
