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 black zinc-coated hat finish. This design enhances rotor durability and braking efficiency by promoting heat dissipation and reducing brake fade. The vented rotor construction further supports temperature management, making it suitable for trucks like the Ford Ranger and Mazda B-series models requiring reliable braking under load.

Detailed Product Description

This disc brake rotor features a 286 mm outside diameter and a nominal thickness of 26 mm, with a discard thickness of 24.5 mm to ensure safe replacement intervals. The rotor is vented and incorporates both drilled holes and slots on the surface, which help to dissipate heat and remove brake dust and gases during operation. The zinc black hat finish provides corrosion resistance, while the rust-resistant coating extends the rotor's service life. The rotor is designed with a 5-bolt hole pattern and a 114.3 mm bolt circle diameter, matching the specifications for Ford Ranger and Mazda B2300, B3000, and B4000 trucks. The directional brake surface optimizes water and debris evacuation, maintaining consistent braking performance in various driving conditions.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Ford Ranger and Mazda B-series trucks
• Improves braking performance by reducing heat buildup and brake fade
• Addresses rotor corrosion issues with rust-resistant coatings
• Enhances stopping power in wet or dusty environments with directional slotted and drilled design
• Suitable for trucks used in towing or heavy-duty applications requiring reliable brake cooling

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 24.5 mm before installation. Verify the 5-lug bolt pattern with a 114.3 mm bolt circle diameter matches your vehicle specifications. Clean the rotor surface before installation to remove any protective coatings or residues. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. It is recommended to replace brake pads simultaneously to maintain optimal braking performance.
