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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and precision slots to improve brake pad bite and reduce brake fade. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life. This product line is designed to meet the demands of vehicles like the Acura RDX that require durable and efficient braking components.

Technical Description and Features

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to dissipate heat more effectively during braking. The directional slotted and drilled surface helps channel away water, dust, and gases generated by pad friction, which can improve braking consistency and reduce the risk of brake fade. The rotor’s nominal thickness of 28 mm and outside diameter of 315 mm are matched to the Acura RDX’s specifications, ensuring proper fit and function. The zinc silver hat finish with rust-resistant coating protects against corrosion, especially in harsh weather conditions. The rotor features five bolt holes with a 12.6 mm diameter and a bolt circle diameter of 114.3 mm, compatible with the Acura RDX wheel hub assembly.

Applications and Problem Solving

• Replacement for worn or warped rotors on Acura RDX models
• Improves heat dissipation to reduce brake fade during heavy braking
• Enhances braking performance in wet or dusty conditions with slotted and drilled design
• Prevents rust and corrosion on rotor hats for longer service life
• Maintains proper rotor thickness and dimensions for safe braking operation

Installation Notes and Tips

Ensure the rotor surface is clean and free of any protective coatings before installation. Verify that the rotor matches the vehicle’s bolt pattern and dimensions. Use proper torque specifications when tightening lug nuts to avoid rotor warping. It is recommended to replace brake pads simultaneously to ensure optimal braking performance. Check for any signs of uneven wear or damage on the hub assembly before installing the new rotor.
