When the lever 80 is pulled by the brake line and simultaneously rotates the two-axis feeding device 50, the two axial directions are The feeding device 50 pushes the corresponding sheet 60 inwardly, so that the two opposite sides of the sheet 60 are synchronously clamped on both sides of the brake disc 40 to provide the effect of reducing the bicycle brake.

Although the appearances of the first housing 10 and the second housing 20 are slightly different, the internal structure is the same and the mirrors are correspondingly mirrored to the right and left. Therefore, the first housing 10 and the axial feeding therein are fed. The device 50 is taken as an example and will be described.

The first housing 10 is formed with a through hole 11 and a screw hole 12 from the inside to the outside. The diameter of the through hole 11 is smaller than the diameter of the screw hole 12, and a shoulder is formed between the through hole 11 and the screw hole 12.
