The 422302 rotor benefits from this approach, offering a reliable replacement part that aligns with the performance standards expected in Mercedes-Benz vehicles.

Technical Details and Features

This disc brake rotor is constructed from high-carbon material, which improves wear resistance and reduces the risk of cracking under stress. The vented design allows for better heat dissipation, minimizing brake fade during extended use. The rotor features a non-directional, smooth surface finish that promotes even pad wear and consistent braking response. Additionally, the rust resistant coating helps protect the rotor from corrosion, extending its service life. With a nominal thickness of 22.00 mm and a discard thickness of 19.40 mm, this rotor maintains structural integrity throughout its usable life. The five-bolt hole configuration ensures compatibility with the specified Mercedes-Benz models.

Compatible Vehicles and Common Applications

• Replacement rotor for Mercedes-Benz C300, C350e, C400, E300, and E350
• Addresses issues such as brake noise, vibration, and reduced stopping power
• Suitable for resolving rotor warping and uneven pad wear
• Helps restore braking performance after rotor surface damage or corrosion

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the rotor thickness is within specifications to maintain safe braking performance. Use proper torque settings on the five bolt holes to secure the rotor firmly. This rotor does not include bearings or an ABS tone ring, so confirm compatibility with your vehicle’s existing components. It is recommended to replace brake pads simultaneously to ensure optimal braking efficiency.
