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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and heat dissipation. This product line is designed to reduce brake fade and maintain consistent stopping power under demanding conditions. The zinc silver coating on the rotor hat provides corrosion resistance, extending the rotor's service life.

Technical Specifications and Features

This solid rotor features a nominal thickness of 12.1 mm and a discard thickness of 10 mm, ensuring safe replacement intervals. The rotor’s overall height and height both measure 45.2 mm, with a center hole diameter of 60 mm. It includes five bolt holes with a diameter of 14.1 mm arranged on a 105 mm bolt circle diameter, matching the stud/lug hole pattern for precise fitment. The directional slotted and drilled surface enhances water and debris evacuation, improving braking performance in wet conditions.

Compatible Vehicles and Applications

• Buick Encore
• Chevrolet Cruze and Cruze Limited
• Chevrolet Sonic
• Chevrolet Trax

This rotor is designed specifically for these models, ensuring proper fit and function when replacing worn or damaged brake rotors.

Common Issues Addressed by This Rotor

• Brake fade caused by overheating during extended braking
• Uneven brake pad wear due to poor heat dissipation
• Corrosion and rust buildup on rotor surfaces
• Reduced braking efficiency in wet or debris-prone environments
• Vibration or noise from warped or damaged rotors

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 10 mm before installation. Clean the rotor surface to remove any protective coatings or contaminants. Verify bolt hole alignment with the vehicle’s hub using the 5-bolt, 105 mm bolt circle pattern. Proper torque specifications should be followed to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.
