Details on the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots on the braking surface to improve water, gas, and dust evacuation. This design helps maintain consistent brake pad contact and reduces the risk of brake fade during heavy use. The zinc silver hat finish adds corrosion resistance, extending rotor life especially in harsh environments. This product line is tailored for heavy-duty applications such as the Ford F-250 Super Duty and F-350 Super Duty models.

Product Description and Specifications

This disc brake rotor is vented to allow air circulation between the rotor surfaces, which helps dissipate heat generated during braking. The directional slotted and drilled surface improves braking efficiency by channeling away brake dust and gases, reducing pad glazing and maintaining consistent friction. The rotor’s nominal thickness is 34 mm, with a discard thickness of 32.4 mm, ensuring safe replacement intervals. The zinc silver hat finish provides rust resistance, protecting the rotor hub from corrosion. With eight bolt holes sized at 16.07 mm diameter and a bolt circle diameter of 170 mm, this rotor is designed for secure mounting on compatible Ford Super Duty trucks.

Compatible Vehicles and Common Applications

• Replacement rotor for Ford F-250 Super Duty models
• Replacement rotor for Ford F-350 Super Duty models
• Addresses issues such as brake fade under heavy load
• Helps reduce rotor warping caused by excessive heat
• Improves braking performance in wet or dusty conditions

Installation Notes and Tips

Ensure the rotor surface and hub are clean and free of debris before installation. Verify the rotor thickness is above the discard thickness of 32.4 mm before mounting. Use proper torque specifications for the eight 16.07 mm bolt holes to secure the rotor. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. Directional rotors must be installed following the indicated rotation direction for correct operation.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for fit and function on Ford F-250 and F-350 Super Duty trucks. The rust-resistant zinc silver hat finish enhances durability in corrosive environments. While specific warranty details are not provided, Dynamite Friction products typically undergo rigorous quality control to ensure reliability and safety in heavy-duty braking applications.
