Abstract: A vehicle brake device includes a master cylinder having a master piston moved by servo pressure in a servo chamber and master pressure of a master chamber is changed by movement of the master piston. A mechanical servo pressure generating unit is connected to a high pressure source and the servo chamber, and generates a servo pressure within the servo chamber according to pilot pressure within a pilot chamber based on brake fluid pressure of the high pressure source. An electrical pilot pressure generating unit is connected to the pilot chamber and generates desired pilot pressure within the pilot chamber, and a master chamber-to-pilot chamber brake fluid line connects the master chamber with the pilot chamber so pilot pressure is generated by the pilot pressure generating unit during normal operation of a power supply system, and the master pressure is used as pilot pressure when the power supply system fails.
