Details on the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots on the braking surface. This design helps to reduce brake fade by allowing gases and debris to escape, while also improving water dispersion in wet conditions. The zinc silver coating on the rotor hat provides corrosion resistance, extending the rotor's service life. This product line is tailored for drivers seeking reliable braking performance on Mercedes-Benz vehicles requiring vented rotors with directional braking surfaces.

Technical Specifications and Features

This disc brake rotor is vented, which means it has internal vanes between the two braking surfaces to improve airflow and heat dissipation. The rotor's surface is both drilled and slotted, providing enhanced pad bite and helping to maintain consistent braking under demanding conditions. The rotor has a nominal thickness of 32mm and a discard thickness of 29.4mm, ensuring safe replacement intervals. The hat finish is zinc silver, offering rust resistance, and the rotor features a plain disc finish. It includes 5 bolt holes with a bolt circle diameter of 112mm and a center hole diameter of 67mm, matching the specified Mercedes-Benz fitments.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Mercedes-Benz GL320, GL350, GL450, GL550, ML320, ML350, ML450, ML500, ML550, R320, R350, and R500
• Improves braking performance by reducing brake fade during heavy use
• Helps prevent uneven pad wear caused by rotor surface glazing
• Reduces heat buildup with vented design for longer brake component life
• Minimizes corrosion with rust resistant coating for extended durability

Installation Notes and Tips

Ensure the rotor is installed on compatible Mercedes-Benz models listed in the fitment section. Verify the bolt hole pattern matches the vehicle’s hub (5 bolt holes, 112mm bolt circle diameter). Clean the rotor surface before installation to remove any protective coatings or residues. Use proper torque specifications for lug nuts to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to maintain optimal braking performance.

Quality Assurance

Dynamite Friction manufactures the DFC Brake Rotor - Drilled and Slotted - Silver to meet or exceed OEM specifications for fit, form, and function. The rust resistant zinc silver coating helps protect against corrosion, contributing to the rotor’s longevity. While no specific warranty information is provided, this rotor is designed for reliable performance on Mercedes-Benz GL, ML, and R series vehicles requiring vented, directional rotors with drilled and slotted surfaces.
