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 design helps reduce brake fade and maintain consistent braking performance, especially for vehicles like the Mitsubishi Eclipse and Galant that require reliable stopping power in various driving conditions.

Product Details and Specifications

This disc brake rotor features a vented design that allows air to flow through the rotor, helping to dissipate heat more effectively during braking. The drilled and slotted surface enhances pad cleaning and gas venting, which contributes to improved braking response. The rotor’s nominal thickness is 20 mm, with a discard thickness of 18.4 mm, ensuring a clear maintenance threshold. The zinc silver coating on the hat provides rust resistance, extending the rotor’s service life. With 5 bolt holes and a bolt circle diameter of 114.3 mm, this rotor is specifically designed to fit Mitsubishi Eclipse and Galant models requiring these dimensions.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Mitsubishi Eclipse and Galant
• Improves braking performance by reducing heat buildup and brake fade
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps maintain consistent brake pad contact with the directional slotted and drilled design
• Prevents rust and corrosion with zinc silver hat finish for longer rotor life

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 5-bolt pattern and 114.3 mm bolt circle diameter. Proper torque specifications should be followed to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.

Quality Assurance and Warranty

Dynamite Friction manufactures the 631-72040L rotor to meet OEM specifications for Mitsubishi Eclipse and Galant vehicles. The rust-resistant coating and vented design contribute to durability and consistent braking performance. Warranty details are available through the manufacturer and should be reviewed prior to purchase.
