ABSTRACT:
To provide a vehicle-use brake device capable of performing a by-wire-method control of high accuracy in response to an inner pressure in a passage by using a pressure sensor possessing high resolution while causing no trouble in view of pressure proof performance. A master cylinder and a brake caliper are connected with each other by a main brake passage and a normally-open solenoid open/close valve V1is provided to the passage. A reaction simulator is connected to the passage closer to the master cylinder side than the open/close valve V1by way of a branch passage. A hydraulic modulator is connected to the passage closer to the brake caliper side than the open/close valve V1by way of a supply/discharge passage. A normally-closed solenoid open/close valve V2is provided to the branch passage, while a normally-closed solenoid open/close valve V3is provided to the supply/discharge passage.
