About the DFC Hi-Carbon Alloy GEOMET Coated Rotor - Drilled Line

This rotor is part of the DFC Hi-Carbon Alloy GEOMET Coated Rotor - Drilled product line by Dynamite Friction, which focuses on combining high-carbon alloy materials with GEOMET coating technology. The high-carbon alloy construction enhances rotor strength and wear resistance, while the GEOMET coating provides corrosion protection. The drilled design aids in heat dissipation and helps maintain consistent braking performance, making it suitable for demanding driving conditions on Mercedes-Benz SUVs and performance models.

Technical Specifications and Features

The rotor features a vented design that allows air to flow between the rotor surfaces, effectively reducing heat buildup during braking. With a nominal thickness of 36 mm and a discard thickness of 33.4 mm, this rotor maintains structural integrity throughout its service life. The 375 mm outside diameter and 54.6 mm height are engineered to match the braking system requirements of compatible Mercedes-Benz models. The five bolt holes, each 15.2 mm in diameter, ensure precise mounting and alignment.

Applications and Problem Solving

• Compatible with Mercedes-Benz GL450, GL550, GLE43 AMG, GLE400, GLE500, GLE550e, GLS550, and ML550 models
• Addresses brake fade caused by excessive heat during heavy braking
• Reduces rotor warping and cracking through improved heat dissipation
• Helps maintain consistent braking performance in wet or humid conditions
• Prevents corrosion and extends rotor lifespan with GEOMET coating

Installation Notes and Tips

Ensure the rotor is installed on vehicles matching the specified fitment list to guarantee proper fit and function. Verify that the rotor thickness is within the nominal range before installation and replace if below discard thickness. Use proper torque specifications for the five bolt holes to avoid mounting issues. It is recommended to inspect brake pads and other braking components during rotor replacement to maintain overall system performance.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet OEM standards for fit, form, and function. The GEOMET coating provides additional corrosion resistance, contributing to the rotor's durability. While specific warranty details are not provided, Dynamite Friction products typically adhere to industry quality controls to ensure reliable performance on Mercedes-Benz vehicles.
