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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction is engineered to provide enhanced braking through a combination of drilled holes and slots on the rotor surface. This design improves heat dissipation and helps reduce brake fade under demanding conditions. The silver zinc coating on the rotor hat offers corrosion resistance, extending the rotor's service life, especially in environments prone to rust.

Technical Specifications and Features

This disc brake rotor features a vented design that promotes airflow to maintain cooler operating temperatures during braking. The rotor's surface is both drilled and slotted, which aids in removing brake dust, gases, and water from the contact area, improving brake pad bite and consistency. The rotor has a nominal thickness of 26 mm and a discard thickness of 24 mm, ensuring safe replacement intervals. The directional brake surface is optimized for the correct rotation direction, enhancing performance and wear characteristics.

Applications and Problem Solving

• Replacement rotor for Nissan 720, D21, and Pickup brake systems
• Addresses brake fade caused by overheating during heavy braking
• Helps reduce rust and corrosion on the rotor hat with zinc silver coating
• Improves braking response in wet or dusty conditions with drilled and slotted surface
• Maintains structural integrity with vented rotor design for heat management

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented correctly according to the vehicle’s rotation. Verify that the bolt hole pattern matches the vehicle’s hub (6 bolt holes, 103 mm bolt circle diameter). Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 24 mm. Clean the rotor surface of any protective coatings or oils before mounting to ensure proper brake pad contact.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet OEM specifications for Nissan 720, D21, and Pickup models. The rust-resistant zinc silver finish on the rotor hat helps extend service life. While specific warranty details are not provided, Dynamite Friction products typically adhere to industry standards for durability and performance.
