Details on 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 with a black zinc-coated hat finish. This design improves heat dissipation and reduces brake fade while providing corrosion resistance. The directional surface pattern is intended to optimize braking efficiency for vehicles like the Audi A4 and A4 Quattro, making this rotor suitable for drivers seeking reliable stopping power under various driving conditions.

Technical Specifications and Features

This disc brake rotor is a solid type with an overall height of 39.8mm and an outside diameter of 245mm. It features a plain disc finish with a zinc black hat finish that offers rust resistance. The rotor includes five bolt holes and lug holes, each with a diameter of 15.5mm, arranged on a 112mm bolt circle diameter. The center hole diameter measures 68mm. The nominal thickness is 10mm, with a discard thickness of 8mm, ensuring clear service limits for safe operation.

Applications and Problem Solving

• Replacement rotor for worn or warped brake discs on Audi A4 and A4 Quattro
• Improves heat dissipation to reduce brake fade during heavy braking
• Slotted and drilled design helps evacuate brake dust and gases
• Rust resistant coating prevents corrosion in humid or wet environments
• Directional surface enhances braking consistency and performance

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction as indicated. Verify bolt hole alignment with the vehicle’s hub using the 5-bolt, 112mm bolt circle pattern. Measure rotor thickness before installation to confirm it meets or exceeds the nominal thickness of 10mm and is above the discard thickness of 8mm. Clean the rotor surface to remove any protective coatings or residues before mounting to ensure optimal brake pad contact.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM specifications for fit and function on Audi A4 and A4 Quattro models. The rust resistant zinc black hat finish extends rotor life by protecting against corrosion. While no specific warranty information is provided, adherence to discard thickness and proper installation will maintain safe braking performance.
