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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and precision slots to optimize brake pad contact and heat dissipation. This product line is designed to provide consistent braking performance under demanding conditions, making it suitable for vehicles like the Chevrolet Trailblazer and Saab 9-7x that require dependable stopping power.

Technical Specifications and Features

This disc brake rotor features a nominal thickness of 29 mm and a discard thickness of 27.5 mm, ensuring a long service life before replacement is necessary. The rotor’s 325 mm outside diameter and 54.7 mm overall height are engineered to match OEM specifications for proper fitment. The vented design allows air to flow between the rotor surfaces, reducing the risk of brake fade during extended use. The rotor surface is directional with drilled holes and slots, which help evacuate gases and debris from the braking surface, improving pad bite and reducing noise. The zinc silver hat finish provides corrosion resistance, complemented by an overall rust-resistant coating to extend rotor durability. The rotor mounts with six 13.3 mm diameter bolt holes arranged on a 127 mm bolt circle diameter, matching the stud/lug hole pattern of the specified vehicles.

Applications and Problem Solving

• Replacement rotor for worn or warped rotors on Chevrolet Trailblazer and Saab 9-7x
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps eliminate brake noise and vibration caused by uneven rotor surfaces
• Restores braking performance compromised by rust or corrosion
• Suitable for vehicles requiring vented, drilled, and slotted rotors for enhanced braking

Installation Notes and Tips

Ensure the rotor is compatible with your Chevrolet Trailblazer or Saab 9-7x by verifying the part number 631-47069L and matching bolt pattern specifications. Clean the hub surface before installation to prevent runout. Use proper torque specifications on the six lug bolts to secure the rotor. It is recommended to replace brake pads when installing new rotors to maintain optimal braking performance.
