Product Line Details: DFC Brake Rotor - Drilled and Slotted - Black

The DFC Brake Rotor - Drilled and Slotted - Black line from Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and heat dissipation. The black zinc coating on the hat area provides additional rust resistance, making these rotors suitable for vehicles exposed to varying weather conditions. This product line is designed to meet the demands of trucks and SUVs such as the GMC K1500 and Jeep Wagoneer, where reliable braking under load is critical.

Technical Specifications and Features

This rotor features a vented design that allows air to flow between the rotor surfaces, reducing heat buildup during braking. The drilled and slotted surface helps evacuate gases and debris, maintaining consistent contact with brake pads. The rotor’s overall height is 58.7 mm, with a center hole diameter of 101.7 mm and a bolt circle diameter of 139.7 mm, matching the factory specifications for compatible vehicles. The zinc black hat finish and rust-resistant coating extend the rotor’s service life by protecting against corrosion.

Applications and Problem Solving

• Improves braking performance on Chevrolet Blazer and GMC K1500 models
• Reduces brake fade caused by heat buildup during heavy use
• Minimizes rotor warping and cracking through vented design
• Helps maintain consistent braking feel in wet or corrosive environments
• Addresses uneven pad wear by providing a directional braking surface

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (30.86 mm) before installation
• Clean mounting surface and hub to prevent runout and vibration
• Use proper torque specifications for the 6 lug bolts (15.1 mm diameter)
• Check compatibility with vehicle make and model before installation
• Inspect brake pads and hardware for wear during rotor replacement
