Detailed Product Features and Specifications

This Dynamite Friction rotor features a slotted and drilled surface type that helps to reduce brake fade by allowing gases and heat to escape more efficiently during braking. The directional brake surface is designed to optimize contact with brake pads, improving overall braking response. The rotor’s nominal thickness is 23 mm, with a discard thickness of 21 mm, ensuring it meets safety standards for wear limits. The hat section is finished in zinc silver and includes a rust-resistant coating to protect against corrosion, extending the rotor’s lifespan. With a bolt hole diameter of 16 mm and six bolt holes arranged on a 120 mm bolt circle diameter, this rotor is engineered for a secure and precise fit on Chevrolet Colorado and GMC Canyon models. The center hole diameter measures 71 mm, and the rotor height is 83 mm, matching OEM specifications for these vehicles.

About the DFC Brake Rotor - Drilled and Slotted - Silver Product Line

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that provide enhanced braking performance through improved heat dissipation and gas evacuation. The drilled and slotted design reduces the risk of brake fade under demanding conditions, making it suitable for trucks like the Chevrolet Colorado and GMC Canyon that may experience heavy braking loads. The silver zinc finish and rust-resistant coating contribute to durability and corrosion resistance, supporting long-term use.

Applications and Problem Solving

• Replaces worn or warped rotors on Chevrolet Colorado and GMC Canyon models
• Addresses brake fade caused by excessive heat buildup during heavy braking
• Reduces brake noise and vibration through improved rotor surface design
• Prevents rust and corrosion that can compromise braking performance
• Ensures consistent braking response with directional slotted and drilled surface

Installation Notes and Tips

Ensure the rotor surface and hub are clean and free of debris before installation. Verify that the rotor thickness is above the discard thickness of 21 mm before mounting. Use proper torque specifications for the six lug bolts to secure the rotor firmly. The directional surface requires correct orientation during installation to maintain optimal braking performance. It is recommended to replace brake pads when installing new rotors to ensure even wear and maximum efficiency.
