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

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots to optimize brake pad contact and heat dissipation. This product line is designed to reduce brake fade and maintain consistent stopping power, particularly suited for vehicles requiring reliable performance under varied driving conditions. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life.

Technical Specifications and Features

This solid rotor features a directional surface type with both drilled holes and slots, which help to evacuate gases, dust, and water from the braking surface. The rotor’s nominal thickness is 10 mm, with a discard thickness of 8.3 mm, ensuring clear service limits for safety. The rotor’s 5-bolt hole configuration with a 112 mm bolt circle diameter matches the wheel hub specifications of the listed Mercedes-Benz models. The zinc silver hat finish offers rust resistance, while the plain disc finish maintains a clean braking surface.

Applications and Problem Solving

• Replaces worn or warped rotors on compatible Mercedes-Benz models
• Improves braking performance by reducing heat buildup and brake fade
• Addresses issues with brake noise and vibration caused by uneven rotor surfaces
• Helps maintain consistent brake pad contact for smoother stops
• Prevents rust and corrosion on rotor hats for longer durability

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (8.3 mm) before installation
• Clean rotor surface and hub mounting area to prevent uneven wear
• Use proper torque specifications for the 5 lug bolts with 15 mm diameter
• Check compatibility with vehicle model and year before installation
• Consider replacing brake pads simultaneously for optimal performance

Quality Assurance and Warranty

Dynamite Friction manufactures the 631-63003L rotor to meet OEM specifications for fit and function on Mercedes-Benz vehicles. The rust resistant coating and precise machining contribute to consistent braking performance and durability. Warranty details should be confirmed with the point of purchase or manufacturer documentation.
