About the DFC Brake Rotor - Drilled and Slotted - Silver 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 braking efficiency. This product line is designed to provide enhanced cooling and debris removal from the rotor surface, which helps maintain consistent brake performance. The silver zinc coating on the rotor hat offers additional protection against rust, extending the rotor's service life in harsh environments.

Technical Specifications and Features

This disc brake rotor is vented to allow air circulation between the rotor surfaces, reducing heat buildup during braking. The directional surface pattern, featuring both drilled holes and slots, improves water and gas evacuation, which can help prevent brake fade and maintain pad contact. The rotor's nominal thickness is 38 mm, with a discard thickness of 36.4 mm, ensuring safe replacement intervals. The rotor includes 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 fitment.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Ford F-250 Super Duty and F-350 Super Duty trucks
• 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 zinc silver coating
• Restores proper rotor thickness and surface condition for safe braking

Installation Notes and Tips

Ensure the rotor surface and hub are clean and free of debris before installation. Verify the rotor thickness is within specifications, replacing if below the discard thickness of 36.4 mm. Use proper torque specifications for the eight 16.2 mm bolt holes to secure the rotor. The directional slotted and drilled surface should be installed following the rotation direction indicated on the rotor to maintain optimal performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM standards for fit and function on Ford F-250 Super Duty and F-350 Super Duty models. The rust-resistant zinc silver coating helps extend rotor life by protecting against corrosion. While no specific warranty information is provided, the rotor is designed for durability and consistent braking performance under typical operating conditions.
