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 and slotted surfaces with a black zinc-coated hat finish. This product line is designed to provide enhanced heat dissipation and corrosion resistance, making it suitable for heavy-duty applications such as those found in Ford Super Duty trucks and Excursion SUVs. The directional surface pattern optimizes braking performance by channeling gases and debris away from the contact area.

Technical Specifications and Features

This disc brake rotor is vented to improve airflow and reduce heat buildup during braking. The rotor's nominal thickness is 38 mm, with a discard thickness of 36 mm, ensuring a long service life before replacement is necessary. The rotor features eight bolt holes with a diameter of 16.2 mm and a bolt circle diameter of 170 mm, matching the stud/lug hole pattern for secure mounting. The overall diameter measures 331 mm, and the height is 99.5 mm, with a center hole diameter of 129.2 mm. The rotor surface is finished plain, while the hat is coated in black zinc to resist rust and corrosion.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Ford Excursion, F-250 Super Duty, and F-350 Super Duty
• Improves heat dissipation to reduce brake fade during heavy towing or hauling
• Slotted and drilled surface helps remove brake dust and water for consistent braking
• Rust resistant coating extends rotor life in harsh weather conditions
• Directional design enhances braking efficiency and pad contact

Installation Notes and Tips

Ensure the rotor is installed with the directional surface pattern oriented correctly according to the vehicle’s rotation direction. Verify that the bolt hole pattern matches the hub assembly (8 holes, 16.2 mm diameter, 170 mm bolt circle). Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 36 mm. Clean the rotor surface of any protective coatings or oils before mounting to ensure optimal brake pad contact.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for Ford Super Duty trucks and Excursion models. The rust resistant coating and zinc black hat finish provide added durability against corrosion. While no specific warranty information is provided, the rotor’s design and materials support reliable performance under heavy-duty conditions.
