Details on 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 on the braking surface. This design helps to reduce brake fade by allowing gases and heat to escape more efficiently during braking. 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, consistent braking performance with enhanced durability.

Technical Specifications and Features

This disc brake rotor has a nominal thickness of 11 mm and a discard thickness of 9.4 mm, ensuring it meets safety standards for replacement intervals. The rotor's 305 mm outside diameter and 71.5 mm height are designed to match the exact specifications required for Kia Sorento models. The rotor features a plain disc finish with a zinc silver hat finish that resists rust and corrosion. The 5 bolt holes, each 12.6 mm in diameter, and a bolt circle diameter of 114.3 mm ensure secure mounting. The directional slotted and drilled surface improves braking efficiency by enhancing heat dissipation and debris removal.

Common Applications and Problem Solving

• Replacement for worn or warped brake rotors on Kia Sorento
• Improves braking performance under heavy load or towing conditions
• Reduces brake fade caused by overheating during extended braking
• Helps eliminate brake noise and vibration associated with rotor surface issues
• Prevents rust and corrosion buildup that can affect braking efficiency

Installation Notes and Tips

Ensure the rotor is installed on compatible Kia Sorento models matching the specified bolt pattern and dimensions. Verify the discard thickness before installation to confirm the rotor is within safe limits. Clean the rotor surface to remove any protective coatings or contaminants before mounting. Proper torque specifications should be followed for the 5 lug bolts to ensure secure fitment and optimal performance.
