Detailed Product Features and Specifications

The DFC Brake Rotor - Drilled and Slotted - Silver is part of Dynamite Friction's DFC product line, which focuses on delivering rotors with enhanced surface designs to improve braking efficiency and rotor longevity. This rotor features a vented construction that allows air to flow between the rotor faces, reducing heat buildup during heavy braking. The directional slotted and drilled surface helps evacuate gases, dust, and water from the braking surface, which can improve pad contact and reduce brake fade.

The rotor's hat is finished with a zinc silver coating to resist corrosion, extending the rotor's service life. It includes five bolt holes with a 130mm bolt circle diameter and a center hole diameter of 85mm, ensuring proper fitment on compatible vehicles. The nominal thickness is 28mm, with a discard thickness of 26mm, indicating when the rotor should be replaced to maintain safe braking performance.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Audi Q7, Porsche Cayenne, and Volkswagen Touareg
• Improves heat dissipation to reduce brake fade during extended braking
• Helps eliminate brake noise and vibration caused by uneven rotor surfaces
• Resists rust and corrosion for longer service life in various weather conditions
• Enhances braking performance in wet or dusty environments with slotted and drilled design

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (26mm) before installation
• Clean rotor surface and hub mounting area to prevent uneven wear
• Use proper torque specifications for the 5 lug bolts (130mm bolt circle diameter)
• Inspect brake pads for wear and replace if necessary to optimize braking performance
• Follow vehicle manufacturer guidelines for brake system maintenance
