Details on the DFC Brake Rotor - Drilled and Slotted - Black Line

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that feature a combination of drilled holes and slots on the braking surface. This design improves heat dissipation and helps reduce brake fade under demanding conditions. The zinc black hat finish adds a layer of rust resistance, making these rotors suitable for vehicles exposed to varying weather conditions. This product line is tailored for drivers seeking a balance between performance and durability on their Chevrolet Blazer, GMC Jimmy, or similar models.

Technical Specifications and Features

This vented rotor measures 295 mm in outside diameter and 95.3 mm in height, providing a robust braking surface. The nominal thickness of 20 mm ensures structural integrity, while the discard thickness of 18.5 mm indicates when replacement is necessary. The rotor features a directional surface type with both drilled holes and slots, which aids in debris removal and heat management. The zinc black hat finish and rust resistant coating protect against corrosion, extending the rotor's service life. The bolt pattern includes five holes with a 13.3 mm diameter and a bolt circle diameter of 120.6 mm, matching the factory specifications for compatible vehicles.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Chevrolet Blazer and GMC Jimmy
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps maintain consistent braking performance in wet or corrosive environments
• Addresses rotor surface damage caused by rust or scoring
• Compatible upgrade for Isuzu Hombre and Oldsmobile Bravada brake systems

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 18.5 mm before installation. Clean the hub surface to remove rust or debris for proper rotor seating. Use the correct torque specifications for the 5 lug bolts with 13.3 mm diameter holes. The directional drilled and slotted surface requires installation in the correct rotation direction to maintain optimal performance. Verify compatibility with your specific vehicle model and year before installation.
