Detailed Product Features and Specifications

This DFC Brake Rotor features a solid disc design with a directional surface that is both drilled and slotted. The drilled holes and slots help to reduce brake fade by allowing gases and debris to escape, while also improving water dispersion in wet conditions. The rotor’s nominal thickness is 10 mm, with a discard thickness of 8.3 mm, ensuring a clear service life indicator for maintenance. The rotor’s hat is finished in zinc silver, providing corrosion resistance, complemented by an overall rust-resistant coating on the rotor surface. The rotor includes five bolt holes with a 112 mm bolt circle diameter, matching the stud/lug hole circle diameter, ensuring proper fitment on compatible Mercedes-Benz models.

DFC Brake Rotor - Drilled and Slotted - Silver Product Line

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction is designed to offer enhanced braking performance through improved heat dissipation and surface friction. This product line focuses on rotors that combine drilled holes and slots with a corrosion-resistant finish, making them suitable for vehicles requiring reliable stopping power and durability. The silver zinc finish on the hat and rust-resistant coating extend rotor life, particularly in environments prone to moisture and corrosion.

Applications and Problem Solving

• Reduces brake fade during extended or aggressive braking
• Improves braking response in wet or humid conditions
• Helps prevent rotor warping caused by excessive heat buildup
• Maintains consistent braking performance on Mercedes-Benz 300 and 500 series models
• Addresses corrosion issues with rust-resistant coatings

Installation Notes and Tips

Ensure the rotor thickness is measured before installation; replace if below the discard thickness of 8.3 mm. Confirm bolt hole alignment with the vehicle’s hub using the 112 mm bolt circle diameter and five-lug pattern. Clean the rotor surface of any protective coatings or oils before mounting to ensure optimal brake pad contact. Directional rotors must be installed with the correct rotation direction to maintain performance benefits.

Quality Assurance

Dynamite Friction manufactures the 631-63003R rotor to meet or exceed OEM specifications for fit and function on compatible Mercedes-Benz models. The rust-resistant coating and zinc silver hat finish contribute to long-term durability. While no specific warranty information is provided, the product is designed for professional automotive use and quality standards consistent with the DFC product line.
