- Center hole diameter of 86.8 mm for precise fitment
Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver
The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction offers rotors designed with both drilled holes and slots on the braking surface. This combination helps evacuate gases, dust, and water, improving braking consistency and reducing the risk of brake fade. The silver zinc coating on the rotor hat provides enhanced corrosion resistance, extending the rotor's service life, especially in environments prone to rust.
Technical Specifications and Features
This disc brake rotor is vented, allowing air to flow between the rotor surfaces to dissipate heat more effectively during braking. The rotor's directional surface pattern, featuring both drilled holes and slots, is engineered to optimize pad contact and maintain clean braking surfaces. The rotor measures 308 mm in outside diameter and 104 mm in height, with a nominal thickness of 25.7 mm and a discard thickness of 24.7 mm, ensuring precise fitment and performance for the Ford F-150. The zinc silver finish on the rotor hat provides rust resistance, helping maintain structural integrity over time.
Applications and Problem Solving
- Replacement rotor for worn or warped brake rotors on Ford F-150 trucks
- Improves heat dissipation to reduce brake fade during heavy towing or hauling
- Helps maintain consistent braking performance in wet or dusty conditions
- Addresses rotor corrosion issues with rust-resistant coating
- Enhances brake pad bite and reduces brake noise through slotted and drilled design
Installation Notes and Tips
Ensure the rotor is compatible with your specific Ford F-150 model year and brake system before installation. Clean the hub surface thoroughly to prevent rotor runout. Torque lug nuts to manufacturer specifications using a star pattern to ensure even pressure. It is recommended to replace brake pads when installing new rotors to optimize braking performance and rotor longevity.
Quality Assurance
Dynamite Friction manufactures the 631-54146L rotor to meet or exceed OEM specifications for fit, form, and function. The rust-resistant zinc silver coating and vented rotor design contribute to durability and consistent braking performance. Warranty information is available through the manufacturer and should be verified at the time of purchase.
