About the Centric GCX Elemental Protection Disc Brake Rotors - Full Coating Line

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating line focuses on providing rotors with a complete protective coating on both the disc surface and the hat. This full coating helps prevent rust and corrosion, extending the rotor's service life and maintaining consistent braking performance. The vented design with curved vanes enhances cooling efficiency, which is critical for maintaining rotor integrity during repeated braking cycles.

Product Details and Specifications

This disc brake rotor features a smooth surface type and a vented solid rotor design with curved vanes to optimize airflow and heat dissipation. The floating disc mounting system allows for slight movement to reduce stress and improve rotor longevity. The rotor's dimensions, including a 12.992-inch outside diameter and 1.106-inch nominal thickness, are tailored to fit Mercedes-Benz models such as the C230, C320, CLK350, SLK280, SLK300, and SLK350. The fully coated finish on both the disc and hat surfaces provides enhanced protection against environmental elements.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing corrosion and rust buildup on original rotors
• Improving heat dissipation to reduce brake fade during heavy use
• Restoring braking performance on Mercedes-Benz C230, C320, CLK350, SLK280, SLK300, and SLK350 models
• Ensuring proper rotor thickness and fitment for safe braking operation

Installation Notes and Tips

When installing the Centric GCX Elemental Protection Disc Brake Rotor (320.35086F), ensure the rotor is compatible with your specific Mercedes-Benz model. Clean the hub surface thoroughly before mounting to prevent runout. Use proper torque specifications on the 5 lug bolts (0.524 inch diameter) and verify the rotor's floating mounting system is correctly engaged. Since this rotor does not include bearings or an ABS tone ring, reuse existing components if applicable.
