About the DFC Brake Rotor - Drilled and Slotted - Black Product Line

The DFC Brake Rotor - Drilled and Slotted - Black line from Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and heat dissipation. The black zinc coating on the hat area adds corrosion resistance, making these rotors suitable for vehicles exposed to varying weather conditions. This product line is designed to meet the specific braking needs of larger SUVs like the Ford Expedition and Lincoln Navigator, providing a balance of performance and durability.

Technical Details and Specifications

This disc brake rotor features a vented design with a plain disc finish and a zinc black hat finish that resists rust. The rotor measures 342 mm in outside diameter and 55 mm in overall height, with a nominal thickness of 22 mm and a discard thickness of 20 mm to ensure safe replacement intervals. It includes 6 bolt holes with a 16 mm diameter and a bolt circle diameter of 135 mm, matching the factory specifications for compatible Ford and Lincoln models. The directional slotted and drilled surface enhances braking by channeling away gases and debris, improving pad contact and reducing brake fade during heavy use.

Applications and Problem Solving

• Replacement rotor for worn or warped brake discs on Ford Expedition and Lincoln Navigator
• Improves heat dissipation to reduce brake fade during towing or heavy loads
• Helps eliminate brake noise and vibration caused by uneven rotor surfaces
• Resists rust and corrosion for longer service life in harsh environments
• Maintains consistent braking performance under demanding driving conditions

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify that the bolt hole pattern and dimensions match your vehicle’s specifications. Use proper torque settings on lug nuts to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to maintain optimal braking performance. Check rotor thickness regularly and replace when reaching the discard thickness of 20 mm.
