Product Line Details

The DFC Brake Rotor - Drilled and Slotted - Silver is part of Dynamite Friction's DFC line, which focuses on enhanced rotor designs featuring drilled and slotted surfaces. This configuration improves heat dissipation and helps maintain consistent braking performance under demanding conditions. The silver zinc coating on the rotor hat provides additional rust resistance, extending the rotor's service life.

Technical Specifications and Features

This disc brake rotor is vented to allow better airflow and heat management during braking. The rotor features a directional surface with both drilled holes and slots, which aid in debris removal and gas venting to reduce brake fade. The rotor's nominal thickness is 22 mm, with a discard thickness of 19.4 mm, ensuring safe replacement intervals. The rotor hat is finished in zinc silver to resist corrosion, and the plain disc finish complements the drilled and slotted design. It has a 5-bolt hole pattern with a bolt circle diameter of 112 mm and a center hole diameter of 69 mm, matching the specifications required for the listed Mercedes-Benz models.

Applications and Problem Solving

• Replacement rotor for worn or warped brake discs on Mercedes-Benz C250, C300, C350e, C400, E250, E300, and E350
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps maintain consistent braking performance in wet or dusty conditions
• Addresses rotor corrosion issues with rust-resistant zinc silver hat finish
• Supports directional braking surface for optimized stopping power and pad contact

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 19.4 mm before installation. The rotor is designed for a 5-lug bolt pattern with a 112 mm bolt circle diameter, so verify compatibility with your vehicle's hub assembly. Clean the rotor surface of any protective coatings before mounting to ensure proper brake pad contact. Follow manufacturer torque specifications for lug nuts to avoid rotor warping.

Quality Assurance

Dynamite Friction manufactures the 631-63118R rotor to meet OEM specifications for fit and function on compatible Mercedes-Benz models. The rust-resistant zinc silver coating on the rotor hat enhances durability. While no specific warranty information is provided, the rotor is engineered for consistent performance and longevity when installed and maintained properly.
