Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction offers rotors with enhanced surface designs combining drilled holes and slots. This configuration improves heat dissipation and helps reduce brake fade under demanding conditions. The zinc silver hat finish provides corrosion resistance, extending rotor life. This product line is tailored for drivers seeking reliable braking components compatible with specific vehicle models such as the Mercedes-Benz ML series.

Technical Description and Specifications

This disc brake rotor is a solid type with a nominal thickness of 15 mm and a discard thickness of 13 mm, ensuring a clear service life indicator. The rotor measures 285 mm in outside diameter and 55.6 mm in overall height, fitting precisely on the specified Mercedes-Benz ML models. The rotor surface is both drilled and slotted in a directional pattern, which aids in channeling away gases and debris from the braking surface, improving pad contact and braking consistency. The zinc silver hat finish combined with a rust-resistant coating protects against corrosion, maintaining structural integrity over time. The rotor features 5 bolt holes with a 112 mm bolt circle diameter, matching the OEM specifications for secure installation.

Applications and Problem Solving

• Reduces brake fade during extended or aggressive braking
• Improves heat dissipation to prevent rotor warping
• Enhances braking response and pad bite on Mercedes-Benz ML320, ML350, ML430
• Resists rust and corrosion for longer service life
• Maintains consistent braking performance under varied driving conditions

Installation Notes and Tips

Ensure the rotor is installed on compatible Mercedes-Benz ML320, ML350, or ML430 models. Verify the bolt hole pattern matches the vehicle’s hub (5 bolts, 112 mm bolt circle diameter). Clean the hub surface before installation to prevent uneven rotor seating. Use proper torque specifications for lug nuts to avoid rotor damage. Directional rotors must be installed with the correct rotation direction for optimal performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM standards for fit and function. The rust-resistant coating and zinc silver hat finish contribute to durability and corrosion resistance. While no specific warranty information is provided, the product is designed for reliable performance on Mercedes-Benz ML320, ML350, and ML430 vehicles when installed and maintained properly.
