• Vented rotor design improves heat dissipation during braking
• Outside diameter of 342 mm and inside diameter of 69 mm for exact fit
• Five bolt holes with 15.35 mm diameter for secure mounting
• Height of 62.8 mm compatible with specified Mercedes-Benz models

About the DFC Hi-Carbon Alloy GEOMET Coated Rotor Line

The DFC Hi-Carbon Alloy GEOMET Coated Rotor line by Dynamite Friction features rotors manufactured with a high-carbon alloy for enhanced wear resistance and thermal stability. The GEOMET coating provides corrosion protection, extending rotor life and maintaining performance under various driving conditions. This product line is designed to meet the demands of modern vehicles requiring precise braking components, such as the Mercedes-Benz E300, E350, GLC250, and GLC300.

Technical Details and Compatibility

This disc brake rotor is vented to facilitate better heat management, reducing the risk of brake fade during extended use. The rotor’s 342 mm outside diameter and 69 mm inside diameter ensure proper alignment with the brake caliper and hub assembly. The five bolt holes, each measuring 15.35 mm in diameter, provide secure attachment to the wheel hub. With a nominal thickness of 32 mm and a discard thickness of 29.4 mm, this rotor maintains structural integrity and signals when replacement is necessary to maintain braking safety.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Mercedes-Benz E300 and E350 models
• Improves braking consistency on GLC250 and GLC300 vehicles
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps prevent brake fade during heavy or prolonged braking
• Restores proper rotor thickness for safe braking performance

Installation Notes and Tips

Ensure the rotor surface and hub mounting area are clean and free of debris before installation. Verify the rotor thickness with a micrometer to confirm it meets or exceeds the discard thickness of 29.4 mm. Use proper torque specifications for the five mounting bolts to avoid rotor warping. It is recommended to inspect brake pads and replace them if worn to maintain optimal braking performance with the new rotor.

Quality Assurance and Warranty

Dynamite Friction manufactures the 900-63119 rotor to meet industry standards for durability and performance. The high-carbon alloy construction combined with the GEOMET coating provides corrosion resistance and long service life. Warranty details are available from the manufacturer and should be reviewed prior to installation.
