About the 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 to improve braking efficiency and rotor cooling. This product line is designed to reduce brake fade and maintain consistent performance by allowing gases and heat to escape more effectively. The zinc silver hat finish provides corrosion resistance, extending rotor life especially in environments prone to rust.

Detailed Product Description

This disc brake rotor is vented to facilitate airflow between the rotor surfaces, which helps dissipate heat generated during braking. The directional surface pattern, featuring both drilled holes and slots, aids in removing brake dust, water, and gases, improving pad contact and braking response. The rotor’s nominal thickness is 22 mm, with a discard thickness of 19 mm, ensuring safe replacement intervals. The zinc silver coating on the hat area offers protection against rust, which is critical for maintaining rotor integrity over time. With 5 bolt holes sized at 15 mm diameter and a bolt circle diameter of 130 mm, this rotor is engineered for a secure fit on compatible Dodge Sprinter models.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Dodge Sprinter 2500 and 3500
• Improves braking performance under heavy load or frequent stop conditions
• Reduces brake fade caused by excessive heat buildup
• Helps prevent rust and corrosion on rotor surfaces
• Addresses brake noise and vibration issues related to rotor surface wear

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (19 mm) before installation
• Clean rotor surface to remove any protective coating before mounting
• Torque lug nuts to manufacturer specifications for secure fitment
• Inspect brake pads and calipers during rotor replacement for optimal performance
• Follow directional rotor installation instructions to maintain proper braking function
