Detailed Product Features and Specifications

This Dynamite Friction rotor features a directional surface that is both drilled and slotted, enhancing brake pad contact and helping to evacuate gases, dust, and water for improved braking efficiency. The rotor is vented, allowing air to flow between the rotor faces to dissipate heat and reduce the risk of brake fade during demanding driving conditions. The hat section is finished with a black zinc coating, providing rust resistance and extending the rotor's service life. With a nominal thickness of 26.1 mm and a discard thickness of 24.5 mm, this rotor meets OEM specifications for thickness and durability. The bolt hole diameter is 1/2-20, with five bolt holes arranged on a 114.3 mm bolt circle diameter, ensuring proper fitment on compatible vehicles.

DFC Brake Rotor - Drilled and Slotted - Black Product Line

The DFC Brake Rotor - Drilled and Slotted - Black line from Dynamite Friction focuses on rotors that combine drilled holes and slots with a corrosion-resistant black zinc finish on the hat. This product line is designed to provide enhanced braking performance and durability for trucks and SUVs that require reliable stopping power under varied driving conditions. The directional surface pattern optimizes pad engagement and helps maintain rotor integrity over time.

Applications and Problem Solving

• Replacement rotor for worn or warped rotors on Ford Ranger and Mazda B-series trucks
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps prevent brake pad glazing and uneven wear with slotted and drilled design
• Resists rust and corrosion for longer service life in harsh environments
• Restores braking performance and safety on vented disc brake systems

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 24.5 mm before installation. Clean the rotor surface to remove any protective coating or debris prior to mounting. Verify bolt hole alignment with the 114.3 mm bolt circle diameter and use the correct 1/2-20 lug nuts for secure fitment. It is recommended to replace brake pads when installing new rotors to maintain optimal braking performance. Follow manufacturer torque specifications for all fasteners.

Quality Assurance

Dynamite Friction rotors are manufactured to meet or exceed OEM standards for fit, form, and function. The black zinc coating on the hat provides rust resistance to extend rotor life. While no specific warranty information is provided, this rotor is designed for durability and consistent braking performance on compatible Ford and Mazda trucks.
