DC Brake
The braking force is controlled by a microcontroller. The unleashed spool produces incredible casting distance.
Shimano's "DC (Digital Control) Brake" instantly senses the rotation of the spool and controls the brake using a microcomputer. It is a state-of-the-art braking system that achieves both high casting distance and reduced line trouble.
The mechanism of Shimano's "DC brakes"
The DC (Digital Control) brake instantly senses the line release status, that is, the change in spool rotation, and controls the brake with a microcomputer. Because the strength of the brake can be adjusted instantly, it achieves both outstanding long-casting performance and backlash prevention. For example, as shown in the red brake curve in the diagram, there is almost no brake immediately after release when the spool rotation increases sharply, and the braking force increases sharply when the rotation reaches its peak. After that, the system automatically controls the brake by applying the minimum necessary braking force, making it possible to significantly improve casting distance.
A system that applies the optimal brakes only when necessary.
The "DC Brake" is a cutting-edge braking system that automatically performs advanced control unimaginable with conventional systems. It instantly increases braking force to avoid backlash when it detects irregular changes in spool rotation speed, such as stalling due to headwinds. Furthermore, it intermittently releases braking force to ensure that "final bit of acceleration," providing sophisticated control.
