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 on the braking surface. This design helps to reduce brake fade by allowing gases and heat to escape more efficiently during braking. The silver zinc coating on the rotor hat provides additional protection against rust, making it suitable for vehicles like the Hummer H3 and H3T that may encounter varied driving environments.

Technical Specifications and Features

This rotor is a solid type, not vented, with a directional braking surface that optimizes pad bite and water dispersion. The rotor’s nominal thickness is 12 mm, with a discard thickness of 10.5 mm, ensuring safe replacement intervals. The rotor’s outside diameter measures 312 mm, and it features six bolt holes with a bolt circle diameter of 139.7 mm, matching the factory specifications for the Hummer H3 and H3T. The hat finish is zinc silver, which combined with the rust-resistant coating, helps maintain rotor integrity over time.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Hummer H3 and H3T
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps prevent rust and corrosion in humid or wet conditions
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Enhances braking performance with directional drilled and slotted design

Installation Notes and Tips

Ensure the rotor thickness is checked before installation; replace if below the discard thickness of 10.5 mm. Clean the rotor surface to remove any protective coating before mounting. Confirm bolt hole alignment with the vehicle’s hub using the 6-bolt pattern and 139.7 mm bolt circle diameter. Proper torque specifications should be followed to avoid rotor warping.

Quality Assurance and Warranty

Dynamite Friction manufactures the 631-93001L rotor to meet OEM standards for fit and function on Hummer H3 and H3T models. The rust-resistant coating and zinc silver hat finish contribute to long-term durability. Warranty details should be confirmed with the distributor or manufacturer, as they may vary.
