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 to improve brake pad bite and heat dissipation. The directional surface design enhances water and debris evacuation, which helps maintain consistent braking performance. The zinc silver hat finish and rust-resistant coating extend the rotor’s service life by protecting against corrosion.

Technical Description and Specifications

This disc brake rotor is specifically designed for Kia Sorento vehicles, ensuring proper fitment and optimal braking efficiency. The rotor measures 305 mm in outside diameter and 71.5 mm in height, with a nominal thickness of 11 mm and a discard thickness of 9.4 mm, indicating when replacement is necessary. The rotor features five bolt holes with a diameter of 12.6 mm arranged on a 114.3 mm bolt circle diameter, matching the Sorento’s hub specifications. The drilled and slotted surface type is directional, which aids in heat dissipation and reduces brake fade during heavy braking. The zinc silver hat finish and rust-resistant coating provide additional protection against corrosion, extending the rotor’s durability.

Applications and Problem Solving

• Compatible with Kia Sorento models requiring a 305 mm drilled and slotted rotor
• Helps reduce brake fade caused by overheating during extended braking
• Improves water and debris evacuation for consistent braking in wet conditions
• Addresses rotor corrosion issues with rust-resistant coating and zinc silver hat finish
• Maintains braking performance by indicating discard thickness for timely replacement

Installation Notes and Tips

Ensure the rotor surface is clean and free of any contaminants before installation. Verify the bolt hole pattern and center hole diameter match the vehicle hub. Use proper torque specifications for the five lug bolts to avoid warping. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance. Check rotor thickness regularly and replace when it reaches the discard thickness of 9.4 mm.
