Detailed Product Description

This DFC Brake Rotor - Drilled and Slotted - Silver is designed to meet the demands of heavy-duty braking applications on select Ford and Lincoln trucks and SUVs. The vented rotor construction allows for better heat dissipation, reducing the risk of brake fade during extended use. The drilled and slotted surface enhances water and gas evacuation, improving braking response in wet or high-temperature conditions. The directional design ensures the rotor is installed correctly for optimal performance.

The rotor features a rust-resistant zinc silver coating on the hat to protect against corrosion, extending the service life of the part. With a nominal thickness of 34 mm and a discard thickness of 32.5 mm, this rotor maintains structural integrity under rigorous braking. The 6-bolt hole pattern with a 135 mm bolt circle diameter and 15.5 mm bolt hole diameter ensures precise fitment on compatible Ford and Lincoln models.

DFC Brake Rotor Product Line Information

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled and slotted surfaces with vented construction. This design balances heat management and debris removal, making it suitable for vehicles requiring consistent braking performance under varied driving conditions. The silver zinc coating on the hat adds corrosion resistance, which is important for vehicles exposed to harsh environments.

Applications and Problem Solving

• Compatible with Ford Bronco, Expedition, F-150, and Lincoln Navigator models requiring vented disc brake rotors
• Helps reduce brake fade caused by overheating during towing or heavy braking
• Improves braking performance in wet conditions by evacuating water from the rotor surface
• Minimizes brake dust and gas buildup for smoother pedal feel
• Protects against rust and corrosion to extend rotor lifespan

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented correctly to maintain braking efficiency. Verify that the bolt hole pattern (6 holes, 15.5 mm diameter, 135 mm bolt circle) matches your vehicle’s hub. Measure rotor thickness before installation and replace if below the discard thickness of 32.5 mm. Clean the rotor surface of any protective coatings or oils before mounting brake pads.

Quality Assurance

Dynamite Friction manufactures the 631-54287L rotor to meet or exceed OEM specifications for fit and function. The rust-resistant zinc silver coating on the hat provides added durability against corrosion. While no specific warranty information is provided, this rotor is designed for dependable performance on compatible Ford and Lincoln vehicles.
