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. The silver zinc coating on the rotor hat provides corrosion resistance, extending rotor life. This product line is designed to meet the demands of daily driving and moderate performance use, making it suitable for Ford Focus owners seeking a balance of durability and braking consistency.

Technical Specifications and Features

This disc brake rotor is vented to allow air circulation between the rotor faces, which helps dissipate heat generated during braking. The rotor’s surface is both drilled and slotted, which aids in removing brake dust, gases, and water from the contact area, improving braking response. The rotor has a nominal thickness of 24 mm and a discard thickness of 22.2 mm, indicating when replacement is necessary to maintain safe braking performance.

The rotor’s hat is finished with a zinc silver coating to resist rust and corrosion, while the disc surface has a plain finish. It features a directional brake surface, which means the slots and drilled holes are oriented to optimize braking efficiency when installed correctly. The rotor includes four bolt holes with a diameter of 13.7 mm and a bolt circle diameter of 108 mm, matching the Ford Focus specifications.

Applications and Problem Solving

• Replacement for worn or warped rotors on Ford Focus models
• Improves heat dissipation to reduce brake fade during extended braking
• 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 dust buildup

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented according to the vehicle’s rotation direction for optimal performance. Verify that the bolt hole pattern and dimensions match the Ford Focus specifications before installation. It is recommended to inspect brake pads and hardware during rotor replacement to ensure complete system reliability.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM specifications for fit and function on Ford Focus vehicles. The rust-resistant zinc silver coating helps extend rotor life by preventing corrosion. While no specific warranty information is provided, adherence to discard thickness guidelines ensures safe and reliable braking performance over the rotor’s service life.
