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 heat dissipation. This product line is designed to reduce brake fade and maintain consistent braking under demanding conditions. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life.

Detailed Product Description

This solid disc brake rotor features a drilled and slotted surface type, which helps evacuate gases, dust, and water from the braking surface. The directional design of the brake surface ensures optimal airflow and cooling during operation. With a nominal thickness of 10 mm and a discard thickness of 8.4 mm, the rotor maintains structural integrity and safety throughout its lifespan. The zinc silver hat finish offers rust resistance, protecting the rotor from corrosion in various driving environments. The rotor is designed with four bolt holes and a bolt circle diameter of 114.3 mm, matching the specifications required for compatible Dodge Colt, Mitsubishi Galant, and Mitsubishi Mirage models.

Applications and Problem Solving

• Replacement for worn or warped brake rotors on Dodge Colt, Mitsubishi Galant, and Mitsubishi Mirage
• Improves braking performance by reducing heat buildup and brake fade
• Helps eliminate brake noise and vibration caused by uneven rotor surfaces
• Prevents rust and corrosion on the rotor hat for longer durability
• Maintains consistent braking response under wet or dusty conditions

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify that the rotor thickness is within the nominal range and above the discard thickness limit of 8.4 mm. Use proper torque specifications for the 4 bolt holes with a 114.3 mm bolt circle diameter. It is recommended to inspect brake pads and replace them if worn to ensure optimal rotor performance. Directional rotors must be installed following the indicated rotation direction for correct operation.

Quality Assurance

Dynamite Friction manufactures the 631-72011L rotor to meet industry standards for durability and performance. The rust-resistant zinc silver coating on the rotor hat enhances longevity by protecting against corrosion. While no specific warranty information is provided, this rotor is designed to maintain consistent braking performance for the compatible Dodge and Mitsubishi models listed.
