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 precision slots to improve brake pad bite and reduce heat buildup. The black zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life. This line is designed to meet the demands of daily driving and moderate performance applications for compatible Ford and Mercury vehicles.

Detailed Product Description

This Dynamite Friction disc brake rotor is a solid type rotor with a 301 mm outside diameter and a 58.2 mm overall height, engineered to fit vehicles requiring a 5-lug bolt pattern with 13.7 mm bolt hole diameter and 114.3 mm bolt circle diameter. The rotor's surface features a directional pattern with both drilled holes and slots, which help to evacuate gases and debris from the braking surface, improving pad contact and reducing brake fade. The nominal thickness of 12.1 mm ensures durability, while the discard thickness of 11 mm indicates when replacement is necessary. The rotor hat is finished with a rust-resistant zinc black coating to protect against corrosion and maintain structural integrity over time.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Ford Explorer, Explorer Sport Trac, and Mercury Mountaineer
• Improves braking performance by reducing heat buildup and brake fade
• Addresses brake noise and vibration issues caused by uneven rotor surfaces
• Helps maintain consistent stopping power under varied driving conditions
• Prevents rust and corrosion on rotor hats for longer service life

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 11 mm before installation. Clean the rotor surface to remove any protective coatings or contaminants prior to mounting. Verify the 5-lug bolt pattern with 13.7 mm bolt hole diameter and 114.3 mm bolt circle diameter matches your vehicle specifications. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. Directional rotors should be installed following the indicated rotation direction for optimal performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM specifications for fit and function on Ford Explorer, Explorer Sport Trac, and Mercury Mountaineer vehicles. The rust-resistant zinc black coating on the rotor hat enhances durability. While no specific warranty information is provided, the rotor's design and materials support reliable braking performance when installed and maintained according to vehicle manufacturer guidelines.
