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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots on the braking surface. This design aids in venting gases and debris while maintaining consistent friction. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life. This product line is tailored for drivers seeking reliable braking components compatible with specific vehicle models like the Volvo S60 and XC60.

Technical Description and Specifications

This disc brake rotor features a nominal thickness of 12 mm and a discard thickness of 9.5 mm, ensuring a clear service life indicator for replacement. The rotor's surface is both drilled and slotted in a directional pattern, which helps channel away heat and brake dust, reducing the risk of brake fade during extended use. The rotor has a plain disc finish with a zinc silver coating on the hat to resist rust and corrosion. It includes five bolt holes with a diameter of 15.8 mm and a bolt circle diameter of 108 mm, matching the factory specifications for Volvo S60 and XC60 models. The rotor's outside diameter measures 302 mm, with a height of 43 mm and a center hole diameter of 63.6 mm, ensuring precise fitment and alignment.

Applications and Problem Solving

• Improves braking performance for Volvo S60 and XC60 vehicles
• Reduces brake fade caused by heat buildup during aggressive driving
• Helps prevent rotor warping and cracking through enhanced cooling
• Minimizes rust and corrosion with zinc silver coating on the rotor hat
• Maintains consistent braking feel with directional slotted and drilled surface

Installation Notes and Tips

Ensure the rotor is installed on compatible Volvo S60 or XC60 models matching the part number 631-27058L. Verify that the bolt hole pattern and center hole diameter align with the vehicle hub. Clean the rotor surface before installation to remove any protective coatings or residues. Use proper torque specifications for the 5 lug bolts to avoid rotor distortion. It is recommended to replace brake pads simultaneously to maintain optimal braking performance.
