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 to improve water, gas, and dust evacuation. This design helps maintain consistent brake pad contact and reduces the risk of brake fade under demanding conditions. The zinc silver hat finish and rust-resistant coating extend the rotor's service life by protecting against corrosion, making it suitable for Ford Expedition and Lincoln Navigator vehicles requiring dependable braking components.

Technical Specifications and Features

This disc brake rotor is vented to allow air circulation between the rotor surfaces, which helps dissipate heat generated during braking. The directional slotted and drilled surface improves braking efficiency by channeling away brake dust and gases, reducing pad glazing. The rotor's dimensions, including a 308 mm outside diameter and 47.1 mm height, ensure compatibility with specified vehicle models. The five lug holes with a 135 mm bolt circle diameter and 16.1 mm diameter provide a secure fit on the hub assembly.

Applications and Problem Solving

• Replacement rotor for worn or warped rotors on Ford Expedition and Lincoln Navigator
• Improves braking performance in wet or dusty conditions by evacuating debris and moisture
• Helps reduce brake fade during heavy braking or towing situations
• Prevents rust and corrosion with zinc silver hat finish and rust-resistant coating
• Maintains consistent brake pad contact for smoother stopping power

Installation Notes and Tips

Ensure the rotor surface is clean and free of oil or debris before installation. Verify the rotor thickness is above the discard thickness of 27.7 mm to maintain safe braking performance. Use proper torque specifications for the five lug nuts with 16.1 mm diameter holes and 135 mm bolt circle diameter. It is recommended to replace brake pads when installing new rotors to optimize braking efficiency and rotor lifespan.

Quality Assurance and Warranty

Dynamite Friction manufactures the 631-54176R rotor to meet or exceed OEM specifications for Ford Expedition and Lincoln Navigator vehicles. The rust-resistant coating and zinc silver hat finish contribute to durability and corrosion resistance. Warranty details are provided by the manufacturer and should be reviewed prior to installation.
