DFC Brake Rotor - Drilled and Slotted - Black Product Line

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and reduce heat buildup. The zinc black hat finish provides corrosion resistance, extending rotor life in demanding driving conditions. This product line is tailored for drivers seeking enhanced braking performance with reliable durability.

Detailed Product Description

This disc brake rotor features a vented design that promotes efficient heat dissipation, reducing the risk of brake fade during extended use. The drilled and slotted surface helps channel away water, dust, and gases, maintaining consistent contact between the brake pad and rotor. The rotor’s nominal thickness of 24.89 mm and discard thickness of 23.01 mm ensure it meets OEM specifications for safe operation. The zinc black coating on the hat area offers rust resistance, which is critical for maintaining structural integrity over time. With a 5-lug bolt pattern and 127 mm bolt circle diameter, this rotor is compatible with specific Buick and Cadillac models including the Commercial Chassis, Fleetwood, Riviera, and Seville.

Applications and Problem Solving

• Restores braking performance on Buick LeSabre and Cadillac Seville vehicles
• Reduces brake fade caused by overheating during heavy braking
• Minimizes brake dust and debris buildup for cleaner braking surfaces
• Prevents rust and corrosion on rotor hats for longer service life
• Improves wet weather braking with drilled and slotted design

Installation Notes and Tips

Ensure the rotor surface is clean and free of contaminants before installation. Verify the bolt hole pattern matches the vehicle’s hub assembly (5 lug holes, 13.4 mm diameter, 127 mm bolt circle). Use proper torque specifications for lug nuts to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to maintain optimal braking performance.
