DFC Brake Rotor - Drilled and Slotted - Silver Product Line Details

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots on the braking surface. This design helps to evacuate gases, dust, and water more efficiently, which can improve braking consistency under demanding conditions. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life, especially in harsh environments.

Technical Specifications and Features

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to dissipate heat effectively during braking. The rotor's nominal thickness is 38 mm, with a discard thickness of 36 mm, ensuring safe replacement intervals. The rotor features eight bolt holes with a diameter of 16.2 mm and a bolt circle diameter of 170 mm, matching the Ford Super Duty bolt pattern. The directional surface type with slotted and drilled features enhances braking performance by improving pad bite and reducing brake fade. The rotor's overall diameter is 331 mm, and the height is 94.4 mm, designed to fit precisely on compatible Ford models.

Applications and Problem Solving

• Replaces worn or warped rotors on Ford F-250 Super Duty and F-350 Super Duty trucks
• Improves brake cooling to reduce fade during heavy towing or hauling
• Helps prevent brake pad glazing by evacuating dust and gases
• Reduces rust and corrosion with zinc silver hat finish and rust-resistant coating
• Maintains braking performance in wet or adverse weather conditions

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 36 mm before installation. Clean the rotor surface to remove any protective coating or debris before mounting. Verify bolt hole alignment with the 170 mm bolt circle diameter and use the correct torque specifications for the eight 16.2 mm bolt holes. The directional surface requires installation in the correct rotation direction for optimal performance. Always inspect brake pads and hardware during rotor replacement.
