Product Line Details

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and heat dissipation. This design helps reduce brake fade and maintain consistent braking performance under demanding conditions. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life.

Technical Description and Features

This vented disc brake rotor features a directional surface with both drilled holes and slots, which work together to evacuate gases, dust, and water from the braking surface. The rotor's nominal thickness of 29 mm ensures durability, while the discard thickness of 27.5 mm indicates when replacement is necessary. The rotor's 5-lug bolt pattern with 13 mm diameter holes and a 120.7 mm bolt circle diameter matches factory specifications for Chevrolet Blazer, GMC Jimmy, and other compatible models. The zinc silver hat finish provides rust resistance, helping maintain structural integrity and appearance over time.

Applications and Problem Solving

• Improves braking performance on Chevrolet S10 and GMC Sonoma trucks
• Reduces brake fade during heavy use on Isuzu Hombre and Oldsmobile Bravada
• Helps prevent rotor warping and cracking through enhanced heat dissipation
• Maintains consistent stopping power in wet or dusty conditions
• Restores factory-spec braking feel and safety on compatible vehicles

Installation Notes and Tips

Ensure the rotor surface is clean and free of oil or debris before installation. Verify the bolt hole pattern and center hole diameter match your vehicle’s hub assembly. Use proper torque specifications for the 5 lug nuts to avoid rotor distortion. It is recommended to replace brake pads when installing new rotors to ensure optimal performance and even wear.
