About the DFC Hi-Carbon Alloy GEOMET Coated Rotor Line

The DFC Hi-Carbon Alloy GEOMET Coated Rotor line by Dynamite Friction focuses on combining high-carbon alloy materials with advanced GEOMET coating technology. This combination enhances rotor durability and corrosion resistance, making it suitable for vehicles that require reliable braking under varied driving conditions. The GEOMET grey finish on the rotor hat helps reduce rust formation, extending the rotor's lifespan while maintaining structural integrity.

Product Details and Specifications

This disc brake rotor features a vented design that improves heat dissipation during braking, reducing the risk of brake fade. The rotor's nominal thickness is 30 mm, with a discard thickness of 28 mm, ensuring it can be resurfaced or replaced at the appropriate intervals. The smooth, plain disc finish provides a consistent braking surface, while the Geomet grey coating on the hat offers additional protection against corrosion. With five bolt holes and a bolt circle diameter of 112 mm, this rotor is engineered for secure mounting on compatible Mercedes-Benz models.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Mercedes-Benz EQB 250+, EQB 300, EQB 350, GLA250, and GLB250
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps reduce rust and corrosion-related rotor degradation
• Improves heat management to prevent brake fade during extended use
• Restores braking performance and pedal feel for safer driving

Installation Notes and Tips

Ensure the rotor is compatible with your specific Mercedes-Benz model before installation. Clean the hub surface thoroughly to prevent uneven rotor mounting. Use proper torque specifications for the five lug bolts to secure the rotor firmly. It is recommended to inspect brake pads and replace them if worn to maintain optimal braking performance. Avoid contaminating the rotor surface with grease or oil during installation.
