Technical Description and Specifications

This disc brake rotor features a vented design that enhances heat dissipation during braking, reducing the risk of brake fade. With a nominal thickness of 24 mm and a discard thickness of 22.4 mm, the rotor ensures safe replacement intervals. The 345 mm outside diameter and 79 mm inside diameter are matched to the specific fitment requirements of BMW 7 Series models including the 745i, 745Li, 760i, and 760Li. The rotor includes five bolt holes with a diameter of 16.9 mm, and a height of 67 mm, ensuring proper fit and secure mounting.

Applications and Problem Solving

• Replacement for worn or warped rotors on BMW 745i, 745Li, 760i, and 760Li
• Addresses brake noise and vibration issues caused by uneven rotor surfaces
• Helps prevent brake fade through vented rotor design
• Reduces corrosion-related rotor damage with GEOSPEC coating
• Maintains braking performance under high thermal stress

Installation Notes and Tips

When installing the Dynamite Friction 604-31059 rotor, ensure the rotor thickness is above the discard thickness of 22.4 mm for safe operation. Properly torque the five bolts to the manufacturer’s specifications to avoid rotor warping. It is recommended to inspect brake pads and hardware during installation to ensure optimal braking system performance. The vented design requires clearance for airflow, so verify fitment on BMW 745i, 745Li, 760i, and 760Li models before installation.
