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 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, which helps dissipate heat generated during braking. The rotor's surface is both drilled and slotted, which aids in removing brake dust and gases, reducing brake fade. With a nominal thickness of 34 mm and a discard thickness of 32 mm, the rotor maintains structural integrity throughout its service life. The rotor features seven bolt holes with a diameter of 15.7 mm and a bolt circle diameter of 150 mm, matching the Ford F-150's hub specifications. The overall height and height of 49.5 mm ensure proper fitment and alignment.

Applications and Problem Solving

• Replacement for worn or warped rotors on Ford F-150 trucks
• Improves braking performance under heavy load or towing conditions
• Reduces brake fade caused by overheating during extended braking
• Helps prevent rust and corrosion with zinc silver coating
• Maintains consistent brake pad contact with directional slotted and drilled surface

Installation Notes and Tips

Ensure the rotor is installed on compatible Ford F-150 models matching the bolt pattern and dimensions specified. Clean the hub surface before installation to prevent runout. Torque lug nuts to manufacturer specifications and verify rotor thickness before installation to confirm it meets minimum discard thickness. Directional rotors must be installed with the correct rotation direction for optimal performance.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet OEM standards for fit and function. The rust-resistant zinc silver coating on the rotor hat enhances durability. While specific warranty details are not provided, Dynamite Friction products typically adhere to industry quality controls to ensure reliable braking performance.
