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

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and reduce heat buildup. The silver zinc coating on the rotor hat enhances corrosion resistance, extending rotor life. This product line is designed to meet the demands of daily driving and moderate performance needs, providing a balance between durability and braking efficiency.

Technical Specifications and Features

This rotor features a solid construction with a nominal thickness of 12 mm and a discard thickness of 10 mm, ensuring a clear service life indicator. The drilled and slotted surface type improves water and gas evacuation during braking, which helps maintain consistent friction and reduces brake fade. The rotor’s directional design supports optimal airflow and debris removal. The zinc silver hat finish offers protection against rust, which is critical for maintaining rotor integrity over time. The rotor fits vehicles with a 5-bolt hole pattern, 14 mm bolt hole diameter, and a 115 mm bolt circle diameter, making it compatible with specific Buick, Chevrolet, and GMC models.

Compatible Vehicles and Applications

• Buick Envision, LaCrosse, Regal Sportback, Regal TourX
• Chevrolet Equinox, Malibu, Trailblazer, Trax
• GMC Terrain

This rotor is ideal for replacing worn or damaged rotors on these models, addressing issues such as brake noise, vibration, and reduced stopping power.

Common Issues Addressed by This Rotor

• Brake rotor warping causing pedal pulsation
• Reduced braking efficiency due to worn rotor surface
• Corrosion and rust buildup on rotor hats
• Brake fade from excessive heat during braking
• Uneven brake pad wear caused by rotor surface imperfections

Installation Notes and Tips

Ensure the rotor surface and hub are clean and free of debris before installation. Verify the rotor thickness is above the discard thickness of 10 mm to maintain safety standards. Use proper torque specifications for the 5-lug bolts with 14 mm diameter holes. The directional surface requires correct orientation during installation to optimize performance. It is recommended to replace brake pads when installing new rotors to ensure even wear and braking efficiency.

Quality Assurance

Dynamite Friction manufactures this rotor to meet industry standards for durability and performance. The rust-resistant zinc silver coating on the rotor hat enhances longevity in corrosive environments. While no specific warranty information is provided, the rotor’s design and materials support reliable service life when installed and maintained properly.
