Details on 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 slots on a directional surface. This design improves water, gas, and dust evacuation from the braking surface, which helps maintain consistent braking performance under demanding conditions. The zinc silver hat finish and rust-resistant coating extend rotor life by reducing corrosion, making it suitable for heavy-duty applications like those found in Ford Super Duty trucks and Excursion SUVs.

Technical Specifications and Features

This disc brake rotor is vented to allow air circulation between the rotor surfaces, reducing heat buildup during braking. The rotor’s nominal thickness is 30 mm, with a discard thickness of 28 mm, ensuring safe replacement intervals. The rotor features eight bolt holes with a diameter of 16.1 mm and a bolt circle diameter of 170 mm, matching the stud/lug hole pattern for secure mounting. The directional slotted and drilled surface enhances braking efficiency by improving pad bite and reducing brake fade. The zinc silver hat finish and rust-resistant coating protect against corrosion, which is critical for vehicles exposed to harsh environments.

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
• Helps maintain consistent braking performance in wet or dusty conditions
• Addresses rotor corrosion issues with rust-resistant coating
• Enhances brake pad life by reducing glazing and uneven wear

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (28 mm) before installation
• Clean mounting surface and hub to prevent rotor runout
• Torque lug nuts to manufacturer specifications for secure fitment
• Check compatibility with OEM brake pads for optimal performance
• Inspect calipers and hardware during installation for wear or damage
