Detailed Features and Specifications

The DFC Brake Rotor - Drilled and Slotted - Silver is part of Dynamite Friction's DFC product line, which focuses on delivering reliable braking components with enhanced surface treatments. This rotor combines drilled holes and slots on a plain disc finish to help evacuate gases, dust, and water, improving braking consistency under various driving conditions. The vented rotor design aids in heat dissipation, reducing the risk of brake fade during extended use.

The rotor's hat is coated with a zinc silver finish, providing corrosion resistance to extend the rotor's service life. With a nominal thickness of 24 mm and a discard thickness of 21.5 mm, this rotor meets Volvo's specifications for safe and effective braking. The bolt hole pattern includes four holes with a 12.5 mm diameter and a 114.3 mm bolt circle diameter, ensuring proper fitment on compatible Volvo S40 and V40 models.

Applications and Problem Solving

• Replacement for worn or warped brake rotors on Volvo S40 and V40
• Improves braking performance by reducing heat and gas buildup
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps prevent rust and corrosion with zinc silver coating
• Maintains braking efficiency under wet or demanding conditions

Installation Notes and Tips

When installing the 631-27026L rotor, ensure the rotor surface is clean and free of any protective coatings before mounting. Verify the rotor thickness is above the discard thickness of 21.5 mm to maintain safety standards. Use proper torque specifications for the four 12.5 mm bolt holes to secure the rotor firmly. It is recommended to replace brake pads simultaneously to optimize braking performance and rotor longevity.
