Details on the DFC Brake Rotor - Drilled and Slotted - Black Line

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that feature both drilled holes and slots on the braking surface. This design helps to reduce heat buildup and evacuate gases and debris during braking, which can improve rotor longevity and maintain consistent stopping power. The black zinc coating on the hat area adds an extra layer of rust protection, making it suitable for vehicles exposed to varying weather conditions.

Technical Description and Specifications

This disc brake rotor is manufactured with a nominal thickness of 20 mm and a discard thickness of 18.5 mm, ensuring it meets safety standards for replacement intervals. The rotor’s 336 mm outside diameter and 42.6 mm height are tailored for specific Ford and Lincoln models, including the Bronco, Expedition, F-150, and Navigator. Featuring six bolt holes with a diameter of 15.7 mm and a bolt circle diameter of 135 mm, the rotor fits securely onto the hub. The directional slotted and drilled surface enhances braking performance by improving heat dissipation and reducing brake fade under demanding conditions.

Applications and Problem Solving

• Replacement for worn or warped rotors on Ford Bronco, Expedition, F-150, and Lincoln Navigator
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps prevent rust and corrosion with zinc black hat finish and rust resistant coating
• Maintains consistent braking performance by evacuating gases and debris
• Restores proper rotor thickness and surface condition for safe stopping

Installation Notes and Tips

Ensure the rotor surface and hub are clean and free of debris before installation. Verify that the rotor thickness is above the discard thickness of 18.5 mm before reuse. The directional slotted and drilled surface requires correct orientation during installation to maintain optimal braking performance. Use the six bolt holes with 15.7 mm diameter to secure the rotor firmly. It is recommended to inspect brake pads and hardware during rotor replacement for best results.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM specifications for fit and function on compatible Ford and Lincoln models. The rust resistant coating and zinc black hat finish contribute to extended rotor life. While no specific warranty information is provided, the rotor is designed to comply with industry standards for safety and durability.
