About the DFC Brake Rotor - Drilled and Slotted - Black Line

The DFC Brake Rotor - Drilled and Slotted - Black product line by Dynamite Friction focuses on rotors that combine drilled holes and slots with a corrosion-resistant black zinc finish. This design enhances braking efficiency by allowing gases and heat to escape while maintaining rotor integrity and resistance to rust. The directional surface pattern is optimized for vehicles requiring precise brake response and durability, such as the Ford Explorer and Mercury Mountaineer.

Technical Details and Specifications

This disc brake rotor features a nominal thickness of 30 mm and a discard thickness of 28.5 mm, ensuring it meets safety standards for replacement intervals. The rotor is vented, which means it has internal channels to improve airflow and cooling during braking. The surface is both drilled and slotted in a directional pattern, which helps to clear water, dust, and brake dust from the contact area, improving braking performance in wet or demanding conditions. The rotor’s hat is finished in zinc black, providing a rust-resistant coating that extends the rotor’s lifespan. With a bolt circle diameter of 114.4 mm and 5 bolt holes sized at 13.65 mm, this rotor fits securely on compatible vehicles.

Applications and Problem Solving

• Replacement for worn or warped rotors on Ford Explorer, Explorer Sport Trac, and Mercury Mountaineer
• Improves braking performance in wet or dusty environments with drilled and slotted surface
• Reduces brake fade during heavy braking due to vented design
• Prevents rust and corrosion with zinc black coating for longer rotor life
• Ensures proper fitment and secure mounting with precise bolt hole dimensions

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 28.5 mm before installation. Clean the hub surface to remove rust or debris for proper rotor seating. Use the correct torque specifications for the 5-lug bolts with 13.65 mm diameter holes. The directional drilled and slotted surface should be installed following the rotation direction indicated on the rotor to maintain optimal performance.

Quality Assurance

Dynamite Friction manufactures the 633-54203R rotor to meet or exceed OEM specifications for fit, form, and function. The rust-resistant zinc black coating and vented design contribute to durability and consistent braking performance. Warranty information is available through the manufacturer and should be consulted for coverage details.
