In a brake device, when a piston (38A, 38B) of a slave cylinder (23) seizes at an advanced position, an out-valve (60, 61) is opened to discharge brake fluid in a wheel cylinder (16, 17; 20, 21) to a reservoir (62). Then, an in-valve (54, 56) and the out-valve (60, 61) are both closed, and a pump (6
In a brake device, when a piston (38A, 38B) of a slave cylinder (23) seizes at an advanced position, an out-valve (60, 61) is opened to discharge brake fluid in a wheel cylinder (16, 17; 20, 21) to a reservoir (62). Then, an in-valve (54, 56) and the out-valve (60, 61) are both closed, and a pump (64) is activated. This allows the brake fluid in the reservoir (62) to be supplied to a fluid pressure chamber (39A, 39B) of the slave cylinder (23), enabling a piston (38A, 38B) of the slave cylinder (23), which has seized at the advanced position, to be pushed back to a retreated position. When the seizure of the piston (38A, 38B) is eliminated in this way, the brake fluid pressure generated in the master cylinder (11) can be supplied to the wheel cylinder (16, 17; 20, 21) via the fluid pressure chamber (39A, 39B) of the slave cylinder (23). Accordingly, it is proposed a method of eliminating seizure of a slave cylinder of a brake device capable of the backup of a failure in the slave cylinder (23).

1. A method of eliminating seizure of a slave cylinder of a brake device comprising: a master cylinder which generates a brake fluid pressure by a braking operation by a driver;a wheel cylinder which brakes a wheel;the slave cylinder which is disposed between the master cylinder and the wheel cylinder, and generates a brake fluid pressure in a fluid pressure chamber by a piston operated by an electric motor;an in-valve which controls communication between the fluid pressure chamber of the slave cylinder and the wheel cylinder;an out-valve which controls communication between the wheel cylinder and a reservoir; anda pump which sends brake fluid in the reservoir back to the fluid pressure chamber of the slave cylinder,the method being characterized by comprising a step of:closing both the in-valve and the out-valve, and then operating the pump. 2. A method of eliminating seizure of a slave cylinder of a brake device according to claim 1, further comprising a step of opening the out-valve, and thereby discharging the brake fluid in the wheel cylinder to the reservoir.
