Details on the DFC Brake Rotor - Drilled and Slotted - Silver 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 by allowing gases and heat to escape more effectively during braking. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life, especially in environments prone to rust.

Technical Specifications and Features

This disc brake rotor is vented, which means it has internal vanes between the rotor faces to promote airflow and heat dissipation. The rotor's directional surface pattern, featuring both drilled holes and slots, helps maintain clean brake pad contact by channeling away dust, water, and gases. The rotor measures 250mm in outside diameter with a 61.1mm center hole diameter, ensuring proper alignment on the hub. It includes four bolt holes with a 100mm bolt circle diameter and 12.7mm stud hole diameter, matching the OEM specifications for Nissan NX and Sentra models. The nominal thickness is 18mm, with a discard thickness of 16mm, indicating when the rotor should be replaced to maintain safe braking performance.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Nissan NX, Pulsar NX, and Sentra
• Improves braking response and reduces brake fade under heavy use
• Helps prevent rust and corrosion on rotor hats with zinc silver coating
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Maintains consistent braking performance in wet or dusty conditions

Installation Notes and Tips

Ensure the rotor surface is clean and free of any protective coatings before installation. Verify that the rotor thickness meets or exceeds the discard thickness of 16mm to guarantee safety. Use proper torque specifications for the 4 bolt holes with a 100mm bolt circle diameter to secure the rotor. It is recommended to inspect brake pads and hardware during installation to ensure optimal braking system performance.
