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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled and slotted surface types with a zinc silver hat finish. This combination enhances heat dissipation and reduces brake fade while providing rust resistance. The directional surface design further aids in channeling gases and debris away from the braking surface, making it suitable for performance-oriented applications on compatible Mercedes-Benz models.

Technical Details and Specifications

This disc brake rotor features a nominal thickness of 32 mm and a discard thickness of 29.4 mm, ensuring a long service life before replacement is necessary. The rotor’s vented design allows air to flow between the rotor faces, improving heat dissipation during braking. The drilled and slotted surface helps maintain clean pad contact and reduces the risk of brake fade. The zinc silver hat finish and rust resistant coating protect the rotor from corrosion, extending its durability in various driving conditions. With 5 bolt holes and a bolt circle diameter of 112 mm, this rotor is engineered for precise fitment on Mercedes-Benz C300, E250, and E300 models.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps eliminate brake noise caused by glazed or contaminated rotors
• Restores braking performance on Mercedes-Benz C300, E250, and E300
• Prevents rust and corrosion-related rotor damage

Installation Notes and Tips

Ensure the rotor surface is clean and free of any protective coatings before installation. Verify the rotor thickness is above the discard thickness of 29.4 mm to maintain safe braking performance. Use proper torque specifications for the 5 lug bolts with a 112 mm bolt circle diameter. It is recommended to replace brake pads simultaneously to ensure optimal rotor and pad contact. Check for any signs of hub or wheel bearing wear that could affect rotor alignment.
