About 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 enhance braking efficiency. This design helps to evacuate gases, dust, and water from the rotor surface, improving contact between the brake pad and rotor. The silver zinc coating on the hat area provides corrosion resistance, extending the rotor's service life in various driving conditions.

Technical Specifications and Features

This disc brake rotor features a vented design with a 331 mm outside diameter and a 53.5 mm overall height, ensuring effective heat management during braking. The rotor's surface is both drilled and slotted, which aids in reducing brake fade and maintaining consistent braking performance. The rotor is directional, meaning it is designed to rotate in a specific direction to optimize slot and drill placement for maximum efficiency. The zinc silver finish on the hat area offers rust resistance, helping to maintain structural integrity over time. With 6 bolt holes sized at 16.2 mm and a bolt circle diameter of 132 mm, this rotor fits securely on compatible vehicles.

Applications and Problem Solving

• Replacement for worn or warped rotors on Buick Acadia and Acadia Limited
• Improves braking response on Chevrolet Traverse and GMC Acadia models
• Helps reduce brake fade during heavy braking or towing with Saturn Outlook
• Addresses rotor corrosion issues with rust-resistant coating
• Enhances heat dissipation to prevent premature brake pad wear

Installation Notes and Tips

Ensure the rotor is installed with the correct orientation to maintain the directional surface design. Verify that the bolt hole pattern matches the vehicle’s hub (6 bolts, 16.2 mm diameter, 132 mm bolt circle diameter). Measure rotor thickness before installation; replace if below the discard thickness of 18.4 mm. Clean the rotor surface before mounting to remove any protective coatings or debris. Proper torque specifications should be followed to secure the rotor safely.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet OEM specifications for fit and function. The rust-resistant zinc silver finish helps extend the rotor’s lifespan under normal operating conditions.
