Detailed Product Description

This Dynamite Friction DFC Brake Rotor - Drilled and Slotted - Silver is a disc brake rotor designed specifically for Volvo vehicles including the S60, S80, V60, and XC70. The rotor features a directional surface with both drilled holes and slots, which work together to reduce brake fade by improving heat dissipation and allowing gases and debris to escape during braking. The rotor’s nominal thickness is 22 mm, with a discard thickness of 19 mm, ensuring a clear maintenance threshold for safety. The zinc silver coating on the rotor hat provides rust resistance, helping to maintain structural integrity and appearance over time.

The rotor includes five bolt holes with a diameter of 15.8 mm arranged on a 108 mm bolt circle diameter, matching the factory specifications for the compatible Volvo models. The outside diameter measures 302 mm, and the rotor height is 41 mm, ensuring proper alignment and fitment. The center hole diameter of 63.5 mm allows for accurate centering on the hub, reducing vibration and promoting smooth braking performance.

About the DFC Brake Rotor - Drilled and Slotted - Silver Product Line

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots in a directional pattern. This design is intended to optimize braking efficiency by enhancing pad bite and heat dissipation while maintaining rotor durability. The silver zinc coating on the rotor hat adds corrosion resistance, making these rotors suitable for drivers seeking reliable performance and longevity on their Volvo S60, S80, V60, or XC70.

Common Applications and Problem Solving

• Reduces brake fade during extended or aggressive braking
• Improves braking response and pad bite in wet or dry conditions
• Helps prevent rotor warping caused by excessive heat buildup
• Minimizes rust and corrosion on the rotor hat for longer service life
• Ensures proper fitment and alignment for Volvo S60, S80, V60, and XC70 models

Installation Notes and Tips

When installing the Dynamite Friction 631-27060L rotor, ensure the rotor is mounted with the directional slotted and drilled surface facing the correct rotation direction as indicated by the rotor markings. Verify that the rotor thickness is above the discard thickness of 19 mm before installation. Clean the rotor surface to remove any protective coatings or contaminants prior to brake pad installation. Use the factory-specified torque settings for the 5 lug bolts to ensure secure mounting and avoid rotor warping.
