Details on 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 combine drilled holes and slots to improve braking efficiency by allowing gases and debris to escape. This design supports better heat dissipation and consistent pad contact, which is critical for vehicles like the Nissan Armada, QX56, and TITAN that demand reliable stopping power under various driving conditions.

Technical Description and Specifications

This disc brake rotor features a vented design that promotes airflow between the rotor surfaces, reducing heat buildup during braking. The drilled and slotted surface type is directional, meaning it is engineered to rotate in a specific direction to maximize performance. The rotor’s zinc silver hat finish and rust resistant coating help protect against corrosion, extending the rotor’s service life. With six bolt holes and a bolt circle diameter of 139.7 mm, this rotor is compatible with the specified Nissan and INFINITI models. The nominal thickness of 26 mm ensures durability, while the discard thickness of 24.5 mm indicates when replacement is necessary to maintain safe braking.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Nissan Armada, QX56, and TITAN
• Improves heat dissipation to reduce brake fade during heavy use
• Helps eliminate brake noise and vibration caused by uneven rotor surfaces
• Addresses corrosion issues with rust resistant coating for longer rotor life
• Enhances braking performance in wet or debris-prone environments with drilled and slotted design

Installation Notes and Tips

Ensure the rotor is installed with the directional surface rotating correctly according to the vehicle’s wheel rotation. Verify bolt hole alignment with the vehicle’s hub using the six bolt holes and 139.7 mm bolt circle diameter. Check rotor thickness before installation to confirm it meets or exceeds the nominal thickness of 26 mm and is above the discard thickness of 24.5 mm. Proper torque specifications should be followed to avoid rotor warping or uneven wear.

Quality Assurance and Warranty

Dynamite Friction manufactures the 631-67096L rotor to meet industry standards for durability and performance. The rust resistant coating and zinc silver hat finish contribute to corrosion protection. While specific warranty details are not provided, Dynamite Friction products typically adhere to quality control measures to ensure reliable braking components for Nissan Armada, QX56, and TITAN vehicles.
