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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction offers rotors designed with enhanced surface features to improve braking efficiency. The drilled and slotted design helps reduce brake fade by allowing gases and debris to escape, while the vented rotor construction promotes better heat dissipation. The zinc silver coating on the rotor hat provides corrosion resistance, extending the rotor's service life on Ford Expedition and Lincoln Navigator vehicles.

Technical Specifications and Features

This disc brake rotor is vented to improve airflow and cooling during braking, which helps maintain consistent performance under demanding conditions. The rotor's nominal thickness is 22 mm, with a discard thickness of 19 mm, indicating when replacement is necessary. The rotor measures 342 mm in outside diameter and 51.8 mm in overall height, ensuring proper fitment and compatibility. The directional slotted and drilled surface enhances braking by improving pad bite and reducing heat buildup. The rotor features six bolt holes with a 16 mm diameter and a 135 mm bolt circle diameter, matching the stud/lug hole pattern of the specified vehicles.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Ford Expedition and Lincoln Navigator
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps prevent rust and corrosion with zinc silver coated rotor hat
• Enhances braking response with directional drilled and slotted surface
