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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots on the braking surface. This design helps to reduce brake fade by allowing gases and heat to escape more efficiently during braking. The zinc silver coating on the rotor hat provides corrosion resistance, extending the rotor's service life. This product line is tailored for drivers seeking rotors that maintain performance under demanding conditions while fitting specific vehicle models such as the Chevrolet City Express and Nissan LEAF.

Technical Specifications and Features

This disc brake rotor is vented, which means it has internal vanes between the two friction surfaces to improve airflow and cooling. The rotor's surface is both drilled and slotted, which aids in removing brake dust, water, and gases that can reduce braking efficiency. The rotor is directional, meaning it is designed to rotate in a specific direction to optimize performance. It features a plain disc finish with a zinc silver hat finish that resists rust and corrosion. The rotor has five bolt holes with a bolt circle diameter of 114.3 mm and a stud/lug hole diameter of 12.9 mm, ensuring proper fitment on compatible vehicles.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Chevrolet City Express, Nissan LEAF, and Nissan NV200
• Improves braking performance by reducing heat buildup and brake fade
• Helps eliminate brake noise and vibration caused by uneven rotor surfaces
• Addresses corrosion issues with rust-resistant coating
• Maintains consistent braking under wet or dusty conditions due to slotted and drilled design

Installation Notes and Tips

Ensure the rotor is installed with the correct orientation to match the directional surface design. Verify that the bolt hole pattern and stud/lug hole diameters correspond to the vehicle specifications. It is recommended to inspect brake pads and hardware during installation and replace if necessary to maintain optimal braking performance. Proper torque specifications should be followed when securing the rotor to avoid warping or uneven wear.

Quality Assurance

Dynamite Friction manufactures the 631-67103L rotor to meet or exceed OEM standards for fit, form, and function. The rust-resistant coating and vented design contribute to durability and consistent braking performance. Warranty information is available through the manufacturer and should be consulted for specific coverage details.
