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 protection. The high carbon content improves thermal stability and wear resistance, while the full coating helps prevent rust and extends rotor life. This combination is particularly suited for standard replacement needs on vehicles like the BMW 135i.

Technical Details and Features

The Pagid 355130012 rotor is constructed from gray cast iron, known for its excellent heat dissipation and structural integrity. It features a vented design to allow air flow between the rotor surfaces, reducing heat buildup during braking. The slotted and dimpled surface enhances brake pad bite and helps evacuate gases and debris, improving braking consistency. Both the disc and hat are coated to resist rust, which is critical for maintaining rotor performance over time. Mill balancing ensures minimal vibration and noise during operation. The rotor measures 324 mm in outside diameter with a 75 mm inside diameter and an overall height of 77.20 mm, fitting the BMW 135i precisely.

Compatible Applications and Problem Solving

• Replacement for worn or warped rotors on BMW 135i models
• Addresses brake fade caused by overheating through vented design
• Reduces rust and corrosion issues with fully coated surfaces
• Improves braking response with slotted and dimpled rotor surface
• Eliminates vibration and noise from unbalanced rotors

Installation Notes and Tips

Installation of the Pagid 355130012 disc brake rotor should be performed by qualified personnel to ensure proper fit and safety. The rotor is non-directional, allowing installation on either side of the vehicle. Verify that the mounting bolt hole pattern (5 holes, 120 mm bolt circle diameter) matches the vehicle hub. Ensure the rotor thickness is above the discard thickness of 20.40 mm before installation. Proper torque specifications should be followed when securing the rotor to avoid warping.

Quality Assurance and Warranty

Pagid rotors undergo strict quality control to meet OEM standards for fit, form, and function. The use of high carbon gray cast iron and rust-resistant coatings contributes to long service life and consistent braking performance. Warranty details are provided by the manufacturer and typically cover defects in materials and workmanship under normal use conditions.
