Details on the DFC Brake Rotor - Drilled and Slotted - Silver Product Line

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots on a vented disc design. This configuration helps reduce brake fade by improving heat dissipation and gas evacuation during braking. The zinc silver hat finish adds corrosion resistance, extending rotor life in various driving conditions. This rotor line is suitable for vehicles requiring directional rotors with a plain disc finish and rust-resistant coating.

Technical Description and Compatibility

This disc brake rotor is vented and features a directional surface with both drilled holes and slots, which aid in heat management and debris removal. The rotor’s nominal thickness is 26.3 mm, with a discard thickness of 24.3 mm, ensuring safe replacement intervals. The rotor fits vehicles with a 5-lug bolt pattern, 13.3 mm bolt hole diameter, and a 120.6 mm bolt circle diameter. Compatible makes include Buick, Cadillac, Chevrolet, GMC, and Oldsmobile, specifically models such as the Blazer, Bravada, Eldorado, Jimmy, Riviera, S10, S10 Blazer, S15, S15 Jimmy, Seville, Sonoma, and Toronado.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Improved heat dissipation to reduce brake fade during heavy use
• Corrosion resistance to prevent rust buildup on braking surfaces
• Enhanced braking performance for vehicles with directional rotor requirements
• Addressing uneven pad wear due to rotor surface imperfections

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (24.3 mm) before installation
• Clean rotor surface to remove any protective coatings before mounting
• Verify bolt hole alignment with vehicle hub (5 bolts, 13.3 mm diameter)
• Torque lug nuts to manufacturer specifications to avoid rotor warping
• Check compatibility with brake pads designed for drilled and slotted rotors
