PURPOSE: A precharging apparatus in a hydraulic brake system for a vehicle is provided to call promptly and accurately regardless of surroundings by increasing fuel pressure in a fuel feed system, and to improve comfortableness by reducing noise. CONSTITUTION: A precharging device is a part of a hydraulic brake system of a vehicle, and serves to supply brake fluid under pressure selectively on a brake assembly by a load unit. To activate supply of brake fluid, the load unit is operatively connected to a fuel supply system(16). The precharging device of the hydraulic brake system of the vehicle selectively supplies brake fluid to the brake system by using the load unit. The load unit is preferably formed of a piston unit(10), and the fuel supply system is composed of a fuel injection unit. The piston unit has a fuel piston(11), and a brake fluid piston(12) operatively connected to the fuel piston by a connecting rod(13). The system is stabilized by regulating pressure properly based on the accurate precharge rate.
