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 help evacuate gases and debris. This design supports consistent braking performance and helps maintain rotor surface integrity over time. The silver zinc coating on the rotor hat adds a layer of rust resistance, extending the rotor’s service life in demanding environments.

Technical Details and Specifications

This vented rotor features a directional surface type with both drilled holes and slots, which aid in heat dissipation and reduce brake fade during extended use. The rotor’s nominal thickness is 20 mm, with a discard thickness of 17.5 mm, indicating when replacement is necessary to maintain safe braking. The rotor’s overall height is 43.1 mm, and it includes five bolt holes with a diameter of 15.7 mm, matching the 108 mm bolt circle diameter for secure installation on compatible Volvo models.

Applications and Problem Solving

• Compatible with Volvo XC40, XC40 Recharge, XC90, C40 Recharge, EC40, and EX40 models
• Addresses brake fade caused by overheating during heavy braking
• Helps reduce brake dust accumulation with drilled and slotted surface
• Improves wet weather braking by channeling water away from the rotor surface
• Prevents rust and corrosion on the rotor hat with zinc silver coating

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 17.5 mm before installation. The rotor is designed for vehicles with a 5-lug bolt pattern and a 108 mm bolt circle diameter. Proper torque specifications should be followed when mounting the rotor to avoid warping. Directional rotors must be installed with the correct rotation direction to maintain optimal performance.
