Details on the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction is designed to provide reliable braking performance with enhanced heat dissipation and reduced brake fade. The drilled and slotted surface pattern helps evacuate gases and debris, improving pad bite and overall rotor cooling. The zinc silver hat finish adds a layer of rust resistance, making it suitable for long-term use on Mercedes-Benz ML and R-Class vehicles.

Product Application and Benefits

This disc brake rotor is compatible with Mercedes-Benz ML320, ML350, ML450, ML500, R320, R350, and R500 models. It is ideal for addressing common braking issues such as:

• Brake fade caused by excessive heat buildup
• Uneven pad wear due to debris accumulation
• Corrosion and rust on rotor surfaces
• Reduced braking efficiency from glazed rotors
• Vibration or noise from warped rotors

Installation Notes and Tips

When installing the Dynamite Friction 631-63128L rotor, ensure the rotor surface is clean and free of any protective coatings before mounting. The directional drilled and slotted surface must be installed with the correct rotation direction for optimal performance. Verify bolt hole alignment with the 5-lug, 112 mm bolt circle diameter pattern specific to the compatible Mercedes-Benz models. Check rotor thickness to ensure it meets the nominal 32 mm specification and replace if below the discard thickness of 29.4 mm.

Quality Assurance and Warranty

Dynamite Friction manufactures the 631-63128L rotor to meet or exceed OEM specifications for fit, form, and function. The rust-resistant coating and zinc silver hat finish contribute to durability and corrosion protection. While specific warranty details are not provided, Dynamite Friction products typically undergo rigorous quality control to ensure consistent performance and reliability for Mercedes-Benz ML and R-Class vehicles.
