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 heat dissipation. This design helps reduce brake fade and maintain consistent braking under demanding conditions. The silver zinc coating on the rotor hat enhances corrosion resistance, extending the rotor's service life in various driving environments.

Detailed Product Description

This solid disc brake rotor features a directional surface with both drilled holes and slots, which work together to evacuate gases, dust, and water from the braking surface. The rotor's 285 mm outside diameter and 58.4 mm height ensure proper fitment and compatibility with the specified Ford and Mercury models. The nominal thickness of 12 mm and discard thickness of 11 mm provide clear service limits for maintenance. The zinc silver hat finish offers rust resistance, helping to maintain structural integrity and appearance over time. With 5 bolt holes sized at 14.5 mm and a bolt circle diameter of 114.3 mm, this rotor matches the factory specifications for secure installation.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Ford Explorer, Explorer Sport, Mountaineer, and Ranger
• Improves braking response and reduces brake fade during heavy use
• Helps prevent rust and corrosion on rotor hats for longer durability
• Addresses brake noise and vibration issues caused by uneven rotor surfaces
• Enhances heat dissipation to maintain consistent braking performance

Installation Notes and Tips

Ensure the rotor surface is clean and free of any contaminants before installation. Verify that the rotor thickness meets or exceeds the discard thickness of 11 mm to maintain safety standards. Use proper torque specifications for the 5 lug bolts with 14.5 mm diameter to secure the rotor. Directional rotors must be installed following the indicated rotation direction to optimize performance and longevity.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet OEM specifications for fit and function on compatible Ford and Mercury vehicles. The rust-resistant coating and precision machining contribute to reliable braking performance. Warranty details are provided by the manufacturer and should be reviewed prior to installation.
