Product Line Details

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve braking efficiency and rotor longevity. The black zinc coating on the hat area provides corrosion resistance, making these rotors suitable for vehicles exposed to varying weather conditions. This product line is designed to meet the demands of performance and durability for Mercedes-Benz vehicles requiring reliable braking components.

Technical Specifications and Features

This disc brake rotor is vented to allow air to flow between the rotor surfaces, reducing heat buildup during braking. The directional slotted and drilled surface helps evacuate gases, dust, and water, which can improve braking response and reduce brake fade. The rotor has a nominal thickness of 22mm and a discard thickness of 19.4mm, ensuring safe replacement intervals. The zinc black hat finish offers rust resistance, extending the rotor's service life. With 5 bolt holes spaced on a 112mm bolt circle diameter and a center hole diameter of 67mm, this rotor is designed for precise fitment on specified Mercedes-Benz models.

Applications and Problem Solving

• Restores braking performance on Mercedes-Benz GL320, ML350, and R500 models
• Reduces brake fade caused by overheating during heavy braking
• Improves water and debris evacuation for consistent braking in wet conditions
• Prevents rust and corrosion on rotor hats for longer service life
• Addresses uneven rotor wear and vibration issues

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 19.4mm before installation. Clean the rotor surface to remove any protective coatings or contaminants. Verify bolt hole alignment with the 112mm bolt circle diameter and 5 lug holes. Use proper torque specifications for lug nuts to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM specifications for fit and function on Mercedes-Benz GL, ML, and R series vehicles. The rust resistant coating and vented design contribute to durability and consistent braking performance.
