About the DFC Brake Rotor - Drilled and Slotted - Black Line

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve heat dissipation and reduce brake fade. The black zinc coating on the rotor hat enhances corrosion resistance, extending the rotor's service life. This product line is tailored for drivers seeking reliable braking components that maintain performance under demanding conditions.

Product Details and Specifications

This solid disc brake rotor features a drilled and slotted surface type, which helps evacuate gases, dust, and water from the braking surface, improving contact between the pad and rotor. The rotor’s nominal thickness is 12 mm, with a discard thickness of 10 mm, ensuring clear service limits for safety. The zinc black finish on the hat provides rust resistance, while the plain disc finish maintains consistent friction characteristics. The rotor is directional, designed to optimize braking efficiency when installed correctly. With 5 bolt holes and a bolt circle diameter of 112.2 mm, it fits securely on compatible Audi A4 and A4 Quattro models.

Common Applications and Problem Solving

• Reduces brake fade during aggressive or repeated braking
• Improves heat dissipation to prevent rotor warping
• Minimizes brake dust buildup for cleaner braking surfaces
• Enhances wet weather braking performance by channeling water away
• Provides corrosion resistance to extend rotor lifespan

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented according to the vehicle’s rotation direction for optimal performance. Verify that the rotor thickness meets or exceeds the nominal thickness of 12 mm before installation. Clean the rotor surface to remove any protective coatings or residues prior to mounting. Use proper torque specifications for the 5 lug bolts to secure the rotor firmly.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for Audi A4 and A4 Quattro vehicles. The rust resistant coating and precise machining contribute to consistent braking performance and durability. Warranty details are available from the manufacturer and should be consulted to confirm coverage terms.
