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 gas evacuation. This design helps maintain braking efficiency under demanding conditions, making it suitable for the Chevrolet Astro and GMC Safari applications. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life.

Technical Specifications and Features

This disc brake rotor is vented to allow air circulation between the rotor surfaces, which helps dissipate heat generated during braking. The directional slotted and drilled surface improves water and debris removal from the braking surface, reducing brake fade. The rotor's nominal thickness is 26.4 mm, with a discard thickness of 24.5 mm, ensuring safe replacement intervals. The rotor features a plain disc finish and a zinc silver hat finish that resists rust and corrosion. It includes five bolt holes with a 1/2-20 diameter and a 127 mm bolt circle diameter, matching the factory specifications for Chevrolet Astro and GMC Safari models.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Chevrolet Astro and GMC Safari
• Improves braking performance by reducing heat-related fade
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps maintain consistent brake pad contact with slotted and drilled design
• Prevents rust and corrosion on rotor hats for longer durability

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 24.5 mm before installation. Clean the rotor surface to remove any protective coating or debris prior to mounting. Verify bolt hole alignment with the 127 mm bolt circle diameter and 1/2-20 bolt hole diameter for proper fitment. Use proper torque specifications for the 5 lug holes to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance.
