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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on delivering rotors with enhanced surface features such as drilled holes and slots. These design elements help reduce brake fade by improving heat dissipation and removing debris from the rotor surface. The silver zinc coating on the hat area adds corrosion resistance, making these rotors suitable for long-term use on Acura MDX vehicles.

Technical Details and Specifications

This solid disc brake rotor measures 330 mm in outside diameter and 45.7 mm in overall height, ensuring a precise fit for Acura MDX models. The rotor features a plain disc finish with a zinc silver hat finish, combining durability with corrosion protection. The drilled and slotted surface type is directional, designed to optimize braking performance by channeling heat and gases away from the contact surface. The rotor includes five bolt holes with a diameter of 14.7 mm and a bolt circle diameter of 120 mm, matching the OEM mounting pattern.

Common Applications and Problem Solving

• Replacement for worn or warped brake rotors on Acura MDX
• Improves braking response and reduces brake fade during heavy use
• Helps prevent rust and corrosion buildup on rotor surfaces
• Addresses noise and vibration issues caused by uneven rotor wear
• Enhances overall brake system reliability and safety

Installation Notes and Tips

Ensure the rotor surface and hub are clean and free of debris before installation. Verify that the rotor thickness is above the discard thickness of 9 mm to maintain safe braking performance. Use proper torque specifications for the 5 lug bolts with 14.7 mm diameter to secure the rotor. The directional drilled and slotted surface should be installed following the rotation direction indicated on the rotor to maximize effectiveness.
