The position is such that the anti-locking controller can take the position of the recompression piston 46 to further control the operation of the oil body controller. In actual implementation, the structure of the piston pushing body 344 and the moving end brake piece 343 may be other shapes. The piston position detector 54 may use other position detectors, and the magnet 541 may be fixed to the double pressure. The bottom end of the piston 46 is to maintain the tightness of the oil storage space 41, and should not be limited thereto.

It can be seen from the above description that the bicycle disc anti-locking brake system and the method thereof have the following effects:

First, the anti-lock effect is generated: the anti-locking controller can analyze the lock detector Detecting information to determine whether the bicycle is locked or not, and controlling the oil body controller when the bicycle is locked, so that the tire of the bicycle repeatedly generates rolling and braking, and the bicycle is prevented from being locked by the tire. situation.

The anti-locking controller can quickly determine whether the bicycle is locked when the bicycle is braked, and the oil can be quickly controlled. The body controller produces an anti-tire lock effect, and the bicycle rider does not feel that the control unit has activated the tire anti-lock function if not carefully observed.

4. Suitable for bicycles: The bicycle disc of the present invention is an electronic component that requires power to be used only by the control unit.
