Product Line Details

The DFC Brake Rotor - Drilled and Slotted - Silver is part of Dynamite Friction's DFC product line, which focuses on rotors designed with enhanced surface features such as drilling and slotting. These features help improve brake pad bite and aid in the evacuation of gases and debris, contributing to more consistent braking under demanding conditions. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life.

Technical Specifications and Features

This disc brake rotor is vented to allow better airflow and heat dissipation, reducing the risk of brake fade during extended use. The rotor's nominal thickness is 32 mm, with a discard thickness of 29.4 mm, ensuring clear service limits for safety. The rotor surface is both drilled and slotted, which helps maintain clean contact with brake pads and improves wet-weather braking performance. The zinc silver hat finish and rust-resistant coating protect against corrosion, especially important for vehicles exposed to moisture and road salts.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Mercedes-Benz ML320, ML350, ML450, ML500, R320, R350, and R500
• Improves heat dissipation to reduce brake fade during heavy braking
• Slotted and drilled surface helps remove brake dust and gases for consistent braking
• Rust-resistant coating prevents premature corrosion and extends rotor life
• Directional design ensures proper installation and optimal braking performance

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction as indicated. Verify that the bolt hole pattern matches the vehicle’s hub (5 bolt holes, 112 mm bolt circle diameter). Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 29.4 mm. Properly torque lug nuts to manufacturer specifications to avoid rotor warping.

Quality Assurance

Dynamite Friction rotors are manufactured to meet or exceed OEM specifications for fit, form, 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 compatible Mercedes-Benz ML and R-Class vehicles.
