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 rotor cooling and reduces brake fade while providing corrosion resistance. The directional surface pattern is engineered to channel gases and debris away from the braking surface, which helps maintain consistent brake pad contact and performance under demanding conditions.

Technical Specifications and Features

This disc brake rotor is vented to allow air circulation between the rotor faces, which helps dissipate heat generated during braking. The rotor’s nominal thickness is 30 mm, with a discard thickness of 28 mm, ensuring a clear maintenance threshold. The rotor’s outside diameter measures 330 mm, and it has a height of 55 mm. The hat is finished in zinc black and treated with a rust-resistant coating to extend service life. The rotor features six bolt holes with a diameter of 16.08 mm and a bolt circle diameter of 140.5 mm, matching the stud/lug hole quantity of six. The center hole diameter is 78.5 mm, ensuring proper fitment on compatible hubs.

Applications and Problem Solving

• Replacement rotor for worn or warped rotors on Chevrolet Tahoe and GMC Yukon XL 1500
• Improves heat dissipation to reduce brake fade during heavy braking
• Slotted and drilled surface helps remove brake dust and gases for consistent pad contact
• Rust-resistant coating protects against corrosion in wet or humid environments
• Directional design optimizes braking performance and rotor longevity

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 28 mm before installation. Clean the rotor surface to remove any protective coating or residue before mounting. Verify bolt hole alignment with the vehicle hub using the 6-bolt pattern and 140.5 mm bolt circle diameter. Proper torque specifications should be followed to avoid rotor warping. This rotor is designed for directional installation; confirm the correct orientation based on the directional surface markings.
