The present invention relates to a rear wheel brake priority device for a hydraulic bicycle. The present invention is to provide safety accidents by allowing hydraulic pressure to block a front wheel brake when a rear wheel brake does not operate. The present invention comprises hydraulic front wheel paths in which the hydraulic pressure is actuated by a front wheel brake lever and to which hydraulic collection paths for collecting bypass hydraulic pressure is connected; hydraulic rear wheel paths separated from the hydraulic front wheel paths and communicating with the hydraulic front wheel paths through a main actuating path so that the hydraulic pressure can be actuated by a rear wheel brake lever; a main piston arranged inside the main actuating path and simultaneously controlling the opening and closing of the hydraulic front and rear wheel paths only by the hydraulic pressure of the hydraulic rear wheel paths; and a sub-piston arranged inside the hydraulic collection paths and controlling the opening and closing of the hydraulic collection paths by the hydraulic pressure of the hydraulic front wheel paths. |
