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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction is engineered to provide enhanced braking efficiency through its vented design and directional surface pattern. The drilled and slotted features help reduce brake fade by improving heat dissipation and removing debris from the rotor surface. This product line is tailored for drivers seeking a balance between performance and durability in their brake components.

Technical Specifications and Features

This disc brake rotor features a vented design that promotes airflow to reduce heat buildup during braking. The rotor’s surface is both drilled and slotted, which aids in water and gas evacuation, improving braking consistency under various conditions. The rotor has a nominal thickness of 22 mm and a discard thickness of 20 mm, ensuring safe replacement intervals. The zinc silver coating on the hat provides rust resistance, extending the rotor’s service life. With 5 bolt holes and a bolt circle diameter of 112 mm, it fits securely on compatible hubs. The directional surface type is designed to optimize braking performance by channeling heat and debris away from the contact area.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Audi A6 Quattro, Volkswagen Passat, and S6
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps maintain consistent braking performance in wet or dusty conditions
• Addresses rotor surface corrosion with rust resistant coating
• Supports safe braking by meeting discard thickness specifications

Installation Notes and Tips

Ensure the rotor surface and hub are clean and free of debris before installation. Verify the rotor thickness is within the nominal range and replace if below discard thickness. Use proper torque specifications for the 5 lug bolts to secure the rotor. The directional surface requires correct orientation during installation to maintain optimal braking performance. It is recommended to inspect brake pads and hardware during rotor replacement for best results.

Quality Assurance

Dynamite Friction manufactures the 631-74023L rotor to meet industry standards for durability and performance. The rust resistant zinc silver finish helps protect against corrosion, extending rotor life. While no specific warranty information is provided, this rotor is designed to comply with OEM fitment and quality requirements for Audi and Volkswagen vehicles.
