Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction offers rotors with enhanced surface features such as drilled holes and slots. These design elements help to evacuate gases, dust, and water from the braking surface, improving brake pad contact and reducing fade. The zinc silver coating on the rotor hat provides corrosion resistance, extending the rotor's service life. This product line is tailored for drivers seeking rotors that balance performance and durability for their Ford Expedition or Lincoln Navigator.

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 rotor's directional surface pattern, combining drilled holes and slots, is engineered to maintain optimal braking efficiency under various driving conditions. The rotor measures 342 mm in outside diameter with a height of 51.8 mm, and it includes six bolt holes with a 16 mm diameter arranged on a 135 mm bolt circle diameter. The nominal thickness is 22 mm, with a discard thickness of 19 mm, ensuring clear service limits for replacement.

Applications and Problem Solving

• Reduces brake fade caused by excessive heat during towing or heavy loads
• Improves braking performance in wet conditions by channeling water away
• Minimizes brake dust accumulation for cleaner rotor surfaces
• Prevents rust and corrosion on the rotor hat for longer service life
• Maintains consistent braking response for Ford Expedition and Lincoln Navigator vehicles

Installation Notes and Tips

Ensure the rotor surface is clean and free of any protective coatings before installation. Verify that the rotor thickness meets or exceeds the discard thickness of 19 mm to maintain safety standards. Use the correct torque specifications for the six 16 mm bolt holes arranged on the 135 mm bolt circle diameter. It is recommended to inspect brake pads and other related components during rotor replacement to ensure optimal braking system performance.

Quality Assurance

Dynamite Friction manufactures the 631-54181L rotor to meet industry standards for durability and performance. The rust-resistant zinc silver coating on the rotor hat helps protect against corrosion. While no specific warranty information is provided, this rotor is designed to maintain consistent braking performance for Ford Expedition and Lincoln Navigator vehicles when installed and maintained properly.
