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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that feature a combination of drilled holes and slots on the braking surface. This design improves brake pad bite and helps evacuate gases, dust, and water from the rotor surface. The silver zinc coating on the hat area provides additional protection against rust, extending rotor life in demanding environments. This product line is tailored for vehicles requiring enhanced braking performance with reliable durability.

Technical Description and Specifications

This disc brake rotor is vented to allow better airflow and heat dissipation during braking, reducing the risk of brake fade. The directional drilled and slotted surface improves pad contact and helps maintain consistent braking under heavy use. With a nominal thickness of 30 mm and a discard thickness of 28 mm, the rotor ensures a clear service life indicator. The rotor’s 8-bolt pattern with a 165.1 mm bolt circle diameter and 9/16-18 bolt hole diameter matches the factory specifications for Ford E-150, E-250, and E-350 Econoline vans. The zinc silver hat finish and rust-resistant coating protect against corrosion, which is critical for vehicles exposed to road salt and moisture.

Compatible Vehicles and Applications

• Ford E-150 Econoline (including Club Wagon)
• Ford E-250 Econoline
• Ford E-350 Econoline and E-350 Super Duty (including Club Wagon)
• Ideal for replacement of worn or damaged rotors on these models
• Addresses issues such as brake noise, vibration, and reduced stopping power

Installation Notes and Tips

Ensure the rotor surface is clean and free of any protective coatings before installation. Verify the bolt hole pattern and dimensions match the vehicle specifications. It is recommended to replace brake pads when installing new rotors to maintain optimal braking performance. Proper torque specifications should be followed for all mounting bolts to avoid rotor warping or uneven wear.
