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

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction offers rotors with enhanced surface features including drilled holes and slots. These design elements help evacuate gases, dust, and water from the braking surface, improving overall braking consistency. The black zinc coating on the rotor hat provides additional rust resistance, extending the rotor's service life in demanding conditions.

Technical Specifications and Features

This disc brake rotor is vented to allow air circulation between the rotor faces, which helps dissipate heat generated during braking. The directional slotted and drilled surface improves pad bite and reduces brake fade by maintaining a cleaner contact surface. The rotor’s nominal thickness is 20 mm, with a discard thickness of 18.4 mm, ensuring safe replacement intervals. The rotor’s hat is finished with a zinc black coating to resist corrosion, particularly important for vehicles exposed to moisture and road salts. The rotor features five bolt holes with a 114.3 mm bolt circle diameter and a center hole diameter of 69 mm, matching the Mitsubishi Eclipse and Galant specifications.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Mitsubishi Eclipse and Galant
• Improves braking performance by reducing heat buildup and brake fade
• Helps prevent rust and corrosion on rotor hats for longer durability
• Addresses brake noise and vibration issues caused by uneven rotor surfaces
• Maintains consistent braking under wet or dusty conditions with slotted and drilled design

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 18.4 mm before installation. Clean the rotor surface to remove any protective coating or debris prior to mounting. Verify bolt hole alignment with the vehicle’s hub using the 114.3 mm bolt circle diameter and 5-lug pattern. Proper torque specifications should be followed to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance.

Quality Assurance

Dynamite Friction manufactures the 633-72040R rotor to meet OEM specifications for Mitsubishi Eclipse and Galant models. The rust-resistant zinc black coating on the rotor hat enhances durability. While no specific warranty information is provided, Dynamite Friction products are designed for reliable performance and longevity under normal operating conditions.
