Details on 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 slots to improve brake pad bite and reduce heat buildup. This product line is designed to provide enhanced braking efficiency and durability, particularly for trucks like the Ford F-150 that demand consistent performance under load. The silver zinc coating on the rotor hat offers corrosion resistance, extending the rotor's service life.
Technical Specifications and Features
This disc brake rotor is vented to allow better airflow and heat dissipation during braking, which helps prevent brake fade. The rotor's surface is both drilled and slotted, providing channels for gas and dust to escape, improving pad contact and braking response. The rotor has a nominal thickness of 25.7 mm and a discard thickness of 24.7 mm, ensuring it meets safety standards for replacement. The 5-bolt hole pattern with a 135 mm bolt circle diameter and 12x1.75 mm bolt hole diameter matches the Ford F-150's specifications. The zinc silver hat finish offers rust resistance, maintaining the rotor's integrity over time.
Applications and Problem Solving
- Replacement rotor for worn or warped rotors on Ford F-150 models
- Improves braking performance by reducing heat buildup and brake fade
- Addresses brake noise and vibration issues caused by uneven rotor surfaces
- Helps maintain consistent stopping power under heavy load or towing conditions
- Prevents rust and corrosion on rotor hats for longer service life
Installation Notes and Tips
Ensure the rotor thickness is above the discard thickness of 24.7 mm before installation. Clean the rotor surface to remove any protective coating or debris prior to mounting. Verify the 5-lug bolt pattern and 135 mm bolt circle diameter match your Ford F-150 specifications. Use proper torque settings on lug nuts to avoid rotor warping. It is recommended to replace brake pads when installing new rotors for optimal performance.
