About the DFC Brake Rotor - Drilled and Slotted - Black Line

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots to enhance brake pad bite and reduce heat buildup. The black zinc-coated hat finish adds corrosion resistance, making these rotors suitable for drivers seeking reliable braking components with extended durability. This product line is designed to meet the specific braking needs of vehicles like the Mitsubishi Eclipse and Galant.

Product Details and Specifications

This disc brake rotor features a vented design that improves airflow and heat dissipation during braking, reducing the risk of brake fade. The drilled and slotted surface helps evacuate gases, dust, and water, maintaining consistent contact between the rotor and brake pads. With a nominal thickness of 20 mm and a discard thickness of 18.4 mm, the rotor ensures a long service life while maintaining safety standards. The zinc black hat finish and rust-resistant coating protect against corrosion, which is essential for maintaining rotor integrity over time. The rotor’s 5-lug bolt pattern with a 114.3 mm bolt circle diameter fits Mitsubishi Eclipse and Galant models precisely, ensuring proper installation and performance.

Common Issues Addressed by This Rotor

• Brake fade caused by excessive heat buildup during aggressive driving
• Uneven brake pad wear due to poor rotor surface design
• Corrosion and rust on rotor surfaces reducing braking efficiency
• Vibration or noise from warped or damaged rotors
• Reduced braking performance in wet conditions

Installation Notes and Tips

Ensure the rotor surface is clean and free of any protective coatings before installation. Verify the bolt hole pattern and lug hole diameter match your Mitsubishi Eclipse or Galant specifications. It is recommended to replace brake pads when installing new rotors to maintain optimal braking performance. Proper torque specifications should be followed when securing the rotor to avoid warping. Directional rotors must be installed with the correct rotation direction for effective braking.
