Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver is part of Dynamite Friction's DFC product line, which focuses on delivering reliable braking components with enhanced heat management. The rotor's drilled and slotted surface helps reduce brake fade by allowing gases and debris to escape, while the directional design ensures proper rotation for optimal braking efficiency. The rotor is solid rather than vented, providing consistent thickness and strength. The zinc silver hat finish combined with a rust-resistant coating protects against corrosion, extending the rotor's service life.

With a nominal thickness of 14 mm and a discard thickness of 11.4 mm, this rotor meets precise wear limits to maintain safety and performance. The 330 mm outside diameter and 62.9 mm overall height are designed to match the OEM specifications for the listed Mercedes-Benz models. The 5-bolt hole pattern with a 112 mm bolt circle diameter ensures proper fitment and secure mounting.

Applications and Problem Solving

• Replacement for worn or warped rotors on Mercedes-Benz ML and R-Class models
• Improves braking response and reduces brake fade under heavy use
• Addresses rotor corrosion issues with rust-resistant coating
• Helps maintain consistent braking performance with directional slotted and drilled design
• Suitable for vehicles experiencing vibration or noise due to rotor surface wear

Installation Notes and Tips

Ensure the rotor is installed with the directional side facing the correct rotation direction as indicated by the vehicle manufacturer. Verify that the rotor thickness is within the nominal range before installation and replace if below discard thickness. Clean the rotor surface to remove any protective coating or debris prior to mounting. Use proper torque specifications for the 5-bolt mounting pattern to avoid warping or uneven wear.

Quality Assurance and Warranty

Dynamite Friction manufactures the DFC Brake Rotor - Drilled and Slotted - Silver to meet or exceed OEM standards for fit, form, and function.
