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 hat finish adds corrosion resistance, while the vented design helps maintain optimal operating temperatures. This product line is tailored for drivers seeking rotors that balance performance and durability on a range of GM vehicles.

Technical Description and Specifications

This disc brake rotor features a nominal thickness of 26.3 mm and a discard thickness of 24.3 mm, ensuring a clear service life indicator. The rotor’s 261 mm outside diameter and 51.1 mm overall height fit specific GM models requiring a 5-lug bolt pattern with a 115 mm bolt circle diameter. The drilled and slotted surface type is directional, designed to channel gases, dust, and water away from the braking surface, improving pad contact and reducing brake fade. The zinc black hat finish and rust-resistant coating protect against corrosion, extending rotor life in various driving conditions.

Compatible Vehicles and Applications

• Buick models including Century, LeSabre, and Regal
• Cadillac models such as DeVille, Eldorado, Seville, and Fleetwood
• Chevrolet vehicles including Lumina APV and Commercial Chassis
• Oldsmobile models like Cutlass Ciera, Cutlass Cruiser, and Delta 88
• Pontiac models including Bonneville, Grand Prix, and Firebird

This rotor is suitable for drivers looking to replace or upgrade rotors on these specific GM vehicles, ensuring proper fitment and braking performance.

Common Issues Addressed by This Rotor

• Brake fade caused by excessive heat buildup during heavy braking
• Uneven pad wear due to poor rotor surface design
• Corrosion and rust on rotor surfaces reducing braking efficiency
• Vibration or pulsation from warped or worn rotors
• Reduced braking performance in wet or dusty conditions

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 24.3 mm before installation. Clean the rotor surface to remove any protective coatings or debris. Verify the 5-lug bolt pattern with a 115 mm bolt circle diameter matches your vehicle’s hub. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. It is recommended to replace brake pads simultaneously for optimal braking performance.
