Detailed Product Features and Specifications
The DFC Brake Rotor - Drilled and Slotted - Silver is part of Dynamite Friction's DFC line, which focuses on rotors designed to provide consistent braking performance with enhanced heat dissipation. The drilled and slotted surface pattern helps evacuate gases and debris from the brake pad interface, reducing brake fade during heavy use. The vented rotor construction further aids in cooling by allowing air to flow between the rotor faces.
This rotor has a nominal thickness of 22 mm and a discard thickness of 20.7 mm, ensuring it meets safety standards for replacement. The zinc silver hat finish combined with a rust-resistant coating protects against corrosion, extending the rotor's service life. The rotor's six bolt holes and 110 mm bolt circle diameter are designed to match the Hummer H1's factory specifications, ensuring proper fitment and secure installation.
Applications and Problem Solving
- Replacement rotor for worn or warped brake rotors on Hummer H1
- Improves braking response and reduces brake fade under heavy load or off-road conditions
- Helps prevent rust and corrosion on braking surfaces
- Addresses noise and vibration issues caused by uneven rotor surfaces
- Maintains proper rotor thickness for safe braking performance
Installation Notes and Tips
When installing the 631-44000L rotor on your Hummer H1, ensure the rotor surface is clean and free of any protective coatings before mounting. Use proper torque specifications for the six lug bolts to avoid warping. It is recommended to replace brake pads simultaneously to ensure optimal contact and performance. Verify the directional rotor is installed with the correct rotation direction as indicated by the surface pattern.
