Detailed Product Description

This DFC Brake Rotor - Drilled and Slotted - Silver is part of Dynamite Friction's DFC line, which focuses on delivering rotors with enhanced surface designs to improve braking efficiency and rotor longevity. The drilled and slotted surface helps to reduce brake fade by allowing gases and heat to escape more effectively during braking. The rotor is solid rather than vented, providing a consistent braking surface with a plain disc finish and a zinc silver coated hat to resist rust and corrosion.

With a nominal thickness of 10.1 mm and a discard thickness of 8.9 mm, this rotor meets precise specifications to ensure safe replacement intervals. The 280 mm outside diameter and 33 mm height are designed to match the Ford Focus brake system requirements. The rotor features 4 bolt holes with a 13.8 mm diameter and a 108 mm bolt circle diameter, ensuring proper fitment and secure mounting.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Ford Focus
• Improves heat dissipation to reduce brake fade during heavy braking
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps maintain consistent braking performance under varied driving conditions
• Prevents rust and corrosion with zinc silver coated hat finish

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify that the rotor thickness is within the nominal range and above the discard thickness to maintain safety. Use proper torque specifications for the 4 bolt holes to avoid rotor warping. This rotor is directional; install with the correct orientation to maximize performance benefits.

Quality Assurance

Dynamite Friction's DFC Brake Rotor line is manufactured to meet or exceed OEM standards for fit, form, and function. The rust resistant coating on the hat extends rotor life by preventing corrosion. While no specific warranty information is provided, the rotor is designed for durability and consistent braking performance on Ford Focus vehicles.
