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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and precision slots to optimize braking efficiency. This product line is designed to provide enhanced cooling and debris removal, which helps maintain braking performance and rotor longevity. The silver zinc-coated hat finish adds an extra layer of rust resistance, making it suitable for various driving environments.

Product Details and Specifications

This disc brake rotor is vented to allow air circulation between the rotor surfaces, reducing heat buildup during braking. The directional surface pattern, featuring both drilled holes and slots, aids in channeling away gases and dust generated by brake pad contact. The rotor measures 286 mm in outside diameter and 57.6 mm in overall height, with a nominal thickness of 26 mm and a discard thickness of 24.5 mm, ensuring it meets Ford Ranger specifications for safe operation. The rotor includes five bolt holes sized 1/2-20 with a bolt circle diameter of 114.3 mm, matching the vehicle's hub pattern precisely.

Applications and Problem Solving

• Reduces brake fade during heavy or repeated braking
• Improves braking response and pad bite on Ford Ranger models
• Helps prevent rotor warping caused by excessive heat
• Minimizes rust and corrosion with zinc silver hat finish and rust-resistant coating
• Maintains consistent braking performance in wet or dusty conditions

Installation Notes and Tips

Ensure the rotor surface is clean and free of any protective coatings before installation. Verify that the rotor thickness is above the discard thickness of 24.5 mm to maintain safety standards. Use proper torque specifications for the 1/2-20 bolt holes and confirm the rotor is mounted with the directional surface facing outward as indicated. It is recommended to replace brake pads when installing new rotors to optimize braking performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM specifications for the Ford Ranger. The rust-resistant coating and zinc silver hat finish contribute to durability and corrosion protection. While no specific warranty information is provided, the product is designed to comply with industry standards for disc brake rotors.
