Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and heat dissipation. This design helps reduce brake fade and maintain consistent braking performance under demanding conditions. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life, especially in environments prone to rust.

Technical Description and Features

This solid disc brake rotor features a drilled and slotted surface type, which enhances ventilation and helps evacuate gases and debris from the braking surface. The directional design ensures optimal contact with brake pads, improving stopping power and reducing noise. The rotor's 308 mm outside diameter and 25.5 mm height are engineered to match the specifications required for Ford Transit-150, Transit-250, Transit-350, and Transit-350 HD models. The zinc silver hat finish offers rust resistance, protecting the rotor from corrosion and maintaining structural integrity over time.

Applications and Problem Solving

• Compatible with Ford Transit-150, Transit-250, Transit-350, and Transit-350 HD vehicles
• Addresses brake fade caused by excessive heat buildup during heavy braking
• Reduces brake noise and vibration through directional drilled and slotted design
• Helps prevent rust and corrosion on rotor hats for longer service life
• Maintains consistent braking performance under load and frequent stop conditions

Installation Notes and Tips

Ensure the rotor is installed on compatible Ford Transit models matching the specified bolt pattern of 5 lug holes with 12x1.75 mm diameter and 150 mm bolt circle diameter. Verify the rotor thickness before installation; replace if below the discard thickness of 15 mm. Properly clean the rotor surface to remove any protective coatings or debris before mounting. Use appropriate torque specifications for lug nuts to avoid warping the rotor during installation.

Quality Assurance

Dynamite Friction manufactures the 631-54228R rotor to meet OEM specifications for fit and function on Ford Transit vehicles. The rust-resistant zinc silver coating and precision machining ensure durability and reliable braking performance. While no specific warranty information is provided, the rotor is designed to maintain consistent thickness and structural integrity within the discard limits for safe operation.
