Detailed Product Description

This DFC Brake Rotor from Dynamite Friction features a directional surface that is both drilled and slotted, which helps to reduce brake fade by allowing heat and gases to escape more efficiently during braking. The rotor’s nominal thickness is 20 mm, with a discard thickness of 18.5 mm, ensuring a long service life before replacement is necessary. The zinc silver coating on the hat provides rust resistance, helping to maintain structural integrity and appearance over time. With six bolt holes sized at 15.7 mm diameter and a bolt circle diameter of 135 mm, this rotor is designed for secure mounting on compatible Ford and Lincoln models.

DFC Brake Rotor - Drilled and Slotted - Silver Product Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots in a directional pattern. This design improves braking efficiency by enhancing cooling and debris removal from the rotor surface. The silver zinc coating on the hat area adds corrosion resistance, making these rotors suitable for vehicles exposed to varying weather conditions. This product line is tailored for drivers seeking rotors that balance performance and durability for their Ford Bronco, Expedition, F-150, or Lincoln Navigator.

Applications and Problem Solving

• Reduces brake fade during heavy braking or towing
• Improves heat dissipation to prevent rotor warping
• Helps maintain consistent braking performance in wet conditions
• Resists rust and corrosion for longer rotor life
• Compatible with specific Ford and Lincoln models requiring 336 mm diameter rotors

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 18.5 mm before installation. Clean the hub surface to remove rust or debris for proper rotor seating. Use the six 15.7 mm bolt holes to securely mount the rotor, matching the 135 mm bolt circle diameter. Verify directional rotation markings to install the rotor correctly for optimal performance.
