Technical Details and Specifications

This disc brake rotor features a vented design with straight vanes that promote airflow and cooling, helping maintain braking efficiency under stress. The nominal thickness of 0.866 inches (22.000 mm) and discard thickness of 0.764 inches (19.400 mm) provide clear service limits for maintenance. The rotor’s overall height is 2.362 inches (60.000 mm), and it measures 11.811 inches (300.000 mm) in outside diameter, matching factory dimensions for proper fitment. The five lug holes with a 4.409 inch (112.000 mm) bolt circle diameter and a center hole diameter of 2.638 inches (67.000 mm) ensure compatibility with the specified Mercedes-Benz models. This rotor does not include an ABS tone ring or bearings.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing reduced braking performance due to rotor thickness below discard limits
• Eliminating noise and vibration from uneven rotor surfaces
• Improving heat dissipation to prevent brake fade on Mercedes-Benz 400SE and S600 models
• Restoring proper rotor dimensions for safe and reliable braking

Installation Notes and Tips

Ensure the rotor surface is clean and free of rust or debris before installation. Verify the rotor thickness is within nominal specifications and above discard thickness limits. Use proper torque specifications for lug nuts to avoid rotor warping. This rotor is designed for floating disc mounting and requires alignment with the two miscellaneous holes for secure fitment. Bearings and ABS tone rings are not included and should be reused or replaced separately as needed.
