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 delivering rotors with enhanced surface features to improve braking efficiency. The drilled and slotted design helps evacuate gases, dust, and water from the rotor surface, which is critical for maintaining consistent brake performance under heavy loads. The silver zinc coating on the rotor hat provides additional rust resistance, extending the rotor's service life in harsh environments.

Technical Specifications and Features

This disc brake rotor features a vented design that promotes airflow between the rotor faces, reducing heat and minimizing brake fade during extended use. The directional surface pattern combines drilled holes and slots to optimize pad contact and improve wet-weather braking. With an outside diameter of 360 mm and a center hole diameter of 127.2 mm, this rotor fits securely on the hub assembly of compatible Chevrolet and GMC heavy-duty trucks. The rotor includes eight bolt holes with a diameter of 16.2 mm arranged on a 180 mm bolt circle, matching factory specifications for proper fitment.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Chevrolet Silverado 2500 HD and 3500 HD models
• Improves braking performance under heavy load conditions for GMC Sierra 2500 HD and 3500 HD
• Helps reduce brake fade and overheating during towing or hauling with Suburban 3500 HD
• Addresses corrosion issues with rust-resistant zinc silver coating
• Enhances brake pad bite and debris removal with drilled and slotted surface

Installation Notes and Tips

Ensure the rotor is installed on compatible Chevrolet or GMC heavy-duty trucks as specified. Verify that the bolt hole pattern and rotor dimensions match the vehicle’s hub assembly. It is recommended to inspect brake pads and hardware during installation and replace if necessary to maintain optimal braking performance. Proper torque specifications should be followed when securing the rotor to avoid warping or uneven wear.
