• Replacement for worn or warped rotors on Mercedes-Benz CL500, S350, S430, and S500
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps reduce rust buildup that can impair braking efficiency
• Improves heat management to prevent brake fade during extended use
• Restores braking performance to factory specifications

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it is above the discard thickness of 26.0 mm. The coated finish requires no additional treatment but handle the rotor carefully to avoid damaging the coating. Verify compatibility with your specific Mercedes-Benz model and check that the mounting bolt hole pattern and center hole diameter match your vehicle’s hub assembly.
