Abstract: PROBLEM TO BE SOLVED: To provide a vehicle brake device with an input piston and a master piston held at a distance from each other, configured to properly estimate master pressures when the input piston and the master piston are in a separated state and in a contact state, by means of a servo ratio that changes depending on whether they are in the contact state or not.SOLUTION: When a brake pedal is suddenly depressed, a master piston is in contact with an input piston. A master pressure of a first master chamber is generated by a pressure formed by adding a brake depressing force to a servo pressure of a servo chamber. The master pressure is returned to a fourth chamber. A servo pressure is generated in a servo pressure generation chamber together with a pilot pressure in a pressure control chamber. The master pressure can be properly estimated on the basis of the servo pressure, the pilot pressure, and a second servo ratio as a cross-sectional area ratio between the fourth chamber and the servo pressure generation chamber.
