About the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on delivering rotors with enhanced surface features such as drilled holes and slots. These design elements help reduce brake fade by improving heat dissipation and allowing gases and debris to escape more efficiently. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life, especially in environments prone to rust.

Detailed Product Description

This disc brake rotor is specifically designed for the Ram ProMaster City, ensuring compatibility and reliable performance. The vented rotor design promotes airflow between the rotor surfaces, reducing heat buildup during braking. The drilled and slotted surface enhances braking efficiency by maintaining a clean pad surface and improving water dispersion. With a nominal thickness of 28 mm and a discard thickness of 25.5 mm, this rotor meets precise wear limits for safety and performance. The directional surface pattern is engineered to optimize braking in wet conditions by channeling water away from the contact area.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Improves braking performance in wet or humid conditions
• Reduces brake fade during extended or heavy braking
• Addresses corrosion issues with rust-resistant coating
• Restores proper rotor thickness for safe braking operation

Installation Notes and Tips

Ensure the rotor surface is clean and free of oil or debris before installation. Verify the rotor thickness is above the discard thickness of 25.5 mm before mounting. Use the correct torque specifications for the 5 lug bolts with 13.3 mm diameter holes and a 98 mm bolt circle diameter. The directional drilled and slotted surface should be installed following the rotation direction indicated on the rotor for optimal performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for the Ram ProMaster City. The rust-resistant zinc silver hat finish helps extend rotor life by preventing corrosion. While no specific warranty information is provided, the rotor's design and materials support durability and consistent braking performance.
