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 to improve brake pad bite and reduce heat buildup. This product line is designed to provide reliable braking performance with enhanced cooling capabilities, making it suitable for Mercedes-Benz ML series vehicles requiring vented rotors with directional surfaces.

Technical Specifications and Features

This disc brake rotor is vented to allow better airflow and heat dissipation during braking, which helps maintain consistent brake performance and reduces the risk of brake fade. The rotor’s surface is both drilled and slotted, which assists in removing brake dust, gases, and water from the contact area. The rotor has a nominal thickness of 26 mm and a discard thickness of 23 mm, ensuring it meets safety standards for wear limits.

The rotor’s hat is finished with a zinc silver coating to resist rust and corrosion, extending the rotor’s service life. It features a plain disc finish and a directional braking surface, which means it is designed to rotate in a specific direction for optimal performance. The rotor includes five bolt holes with a bolt circle diameter of 112 mm and a center hole diameter of 67 mm, matching the specifications for the Mercedes-Benz ML320, ML350, and ML430 models.

Applications and Problem Solving

• Replaces worn or warped rotors on Mercedes-Benz ML320, ML350, ML430
• Improves heat dissipation to reduce brake fade during heavy braking
• Enhances braking response with slotted and drilled surface design
• Prevents rust and corrosion with zinc silver hat finish
• Maintains consistent braking performance under demanding conditions

Installation Notes and Tips

Ensure the rotor is installed with the directional side facing the correct rotation direction as indicated by the vehicle manufacturer. Verify bolt hole alignment with the 5-lug pattern and 112 mm bolt circle diameter. Check rotor thickness before installation to confirm it meets or exceeds the discard thickness of 23 mm. Properly torque lug nuts to manufacturer specifications to avoid rotor warping.

Quality Assurance

Dynamite Friction rotors are manufactured to meet OEM specifications for fitment and performance. The rust-resistant zinc silver coating helps extend rotor life by preventing corrosion. While no specific warranty information is provided, the product is designed to comply with industry standards for durability and safety on Mercedes-Benz ML320, ML350, and ML430 vehicles.
