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 tailored for drivers seeking rotors that maintain consistent braking performance under demanding conditions.

Technical Specifications and Features

This disc brake rotor features a vented design that promotes airflow to dissipate heat effectively during braking. The drilled and slotted surface helps evacuate gases and debris, reducing brake fade and maintaining pad contact. The rotor’s directional surface ensures proper rotation alignment for optimal performance. With a nominal thickness of 26 mm and a discard thickness of 23 mm, it meets precise wear limits for safety. The zinc silver hat finish offers rust resistance, protecting the rotor’s core components. The rotor fits Mercedes-Benz ML320, ML350, and ML430 models with a 5-lug bolt pattern and a 112 mm bolt circle diameter.

Compatible Vehicles and Applications

• Mercedes-Benz ML320 brake rotor replacement
• Mercedes-Benz ML350 vented disc brake rotor upgrade
• Mercedes-Benz ML430 drilled and slotted rotor installation
• Addressing brake fade and overheating issues
• Replacing worn or warped rotors on compatible models

Installation Notes and Tips

Ensure the rotor is installed with the directional surface rotating correctly according to the vehicle’s forward motion. Verify bolt hole alignment with the 5-lug pattern and 112 mm bolt circle diameter. Check rotor thickness before installation to confirm it meets or exceeds the discard thickness of 23 mm. Proper torque specifications should be followed to avoid rotor warping or uneven wear.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet OEM specifications for fit and function on Mercedes-Benz ML320, ML350, and ML430 models.
