About 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 brake pad bite and reduce gas buildup during braking. The silver zinc coating on the rotor hat provides corrosion resistance, extending rotor life in various driving conditions. This product line is designed to meet the demands of Toyota 4Runner and Tacoma drivers seeking reliable, vented rotors with directional braking surfaces.

Technical Specifications and Features

This disc brake rotor features a nominal thickness of 21.8 mm and a discard thickness of 20 mm, ensuring safe replacement intervals. The rotor is vented to allow airflow between the rotor faces, which helps dissipate heat and reduce brake fade during heavy use. The surface is both drilled and slotted, which aids in removing brake dust and gases, improving overall braking efficiency. The rotor hat is finished with a zinc silver coating to resist rust and corrosion, maintaining structural integrity over time. With six bolt holes and a bolt circle diameter of 139.7 mm, this rotor fits securely on compatible Toyota models.

Applications and Problem Solving

• Improves braking performance on Toyota 4Runner and Tacoma vehicles
• Reduces brake fade during extended or heavy braking
• Helps prevent rotor warping caused by excessive heat
• Minimizes rust and corrosion on rotor hats for longer service life
• Enhances brake pad bite and reduces gas buildup with drilled and slotted design

Installation Notes and Tips

Ensure the rotor surface is clean and free of any protective coatings before installation. Verify that the rotor thickness is above the discard thickness of 20 mm to maintain safety standards. Properly torque the six lug nuts to the manufacturer’s specifications for secure fitment. This rotor is directional; install with the correct orientation to maximize performance benefits. It is recommended to inspect brake pads and hardware during rotor replacement for optimal braking system function.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for Toyota 4Runner and Tacoma models. The rust-resistant zinc silver finish on the rotor hat helps maintain durability in various environments. While no specific warranty information is provided, Dynamite Friction products are engineered for consistent performance and reliability in automotive braking applications.
