DFC Brake Rotor - Drilled and Slotted - Silver Product Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and precision slots to optimize brake pad contact and heat dissipation. This product line is designed to provide consistent braking performance and durability, particularly for heavy-duty applications such as Ford F-250 and F-350 trucks. The silver zinc coating on the rotor hat offers additional rust resistance, extending the rotor's service life in harsh environments.

Detailed Product Description

This disc brake rotor is vented to allow air circulation between the rotor surfaces, which helps prevent brake fade caused by excessive heat. The directional surface pattern, featuring both drilled holes and slots, aids in channeling away gases, dust, and water from the braking surface, improving pad bite and overall braking efficiency. The rotor's nominal thickness is 31.6 mm, with a discard thickness of 30 mm, ensuring a clear maintenance threshold for safe operation. The zinc silver finish on the rotor hat provides corrosion resistance, which is critical for maintaining structural integrity over time. With eight bolt holes sized at 16.3 mm and a bolt circle diameter of 165.1 mm, this rotor is designed to fit securely on compatible Ford truck hubs.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Ford F-250 and F-350
• Improves heat dissipation to reduce brake fade during heavy towing or hauling
• Helps maintain consistent braking performance in wet or dusty conditions
• Addresses rotor corrosion issues with rust-resistant coating
• Restores proper rotor thickness for safe braking operation

Installation Notes and Tips

Ensure the rotor surface and hub mounting area are clean and free of debris before installation. Verify the rotor thickness is above the discard thickness of 30 mm before mounting. Use the correct torque specifications for the eight 16.3 mm bolt holes to secure the rotor properly. This rotor is directional; install it according to the indicated rotation direction to maintain optimal performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for Ford F-250 and F-350 trucks. The rust-resistant zinc silver finish and vented design contribute to long-term durability.
