Hella Pagid OE Two Piece Design Product Line

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. It features a composite construction with a gray cast iron friction ring and an aluminum hat, both fully coated to resist corrosion. The two-piece design enhances thermal management and reduces unsprung weight, aligning with original equipment standards for the BMW 135i.

Detailed Product Description

The Pagid 355120861 disc brake rotor is constructed from gray cast iron for the friction surface, paired with a lightweight aluminum hat. This composite design improves heat dissipation and reduces rotor warping under heavy braking conditions. The rotor is vented, allowing air to flow between the rotor faces to maintain optimal operating temperatures. Both the disc and hat are coated to provide rust resistance, extending the rotor's service life. With a nominal thickness of 25.90 mm and a discard thickness of 24.40 mm, this rotor meets precise specifications for the BMW 135i. The 6-bolt hole pattern and 338 mm outside diameter ensure proper fitment and secure mounting.

Common Applications and Issues Addressed

• Replacement for worn or warped rotors on BMW 135i
• Improves braking consistency and reduces brake fade
• Addresses rotor corrosion and surface rust
• Restores proper rotor thickness for safe braking performance
• Enhances heat dissipation to prevent overheating during aggressive driving

Installation Notes and Tips

Ensure the rotor is compatible with your BMW 135i by verifying the part number 355120861. Clean the hub surface before installation to prevent uneven rotor mounting. Use proper torque specifications on the 6 bolt holes to secure the rotor. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. Check rotor thickness regularly and replace when below the discard thickness of 24.40 mm.

Quality Assurance and Warranty

Pagid rotors are manufactured to meet OE standards with strict quality control processes. The rust-resistant coating and composite construction contribute to durability and long service life. Warranty information should be confirmed with the point of purchase or manufacturer, as it may vary by region.
