PROBLEM TO BE SOLVED: To prevent invasion of air into a master cylinder side by bleeding air from a component downstream of the master cylinder when replacing the component.SOLUTION: An instruction device for externally transmitting a control command to an ECU 101 is connected to a vehicle. Operating the instruction device, a worker causes the ECU 101 to control so as to close normal-open master cut valve 60a and master cut valve 60b (S1). Then the worker replaces a necessary component among components disposed downstream of the master cut valves 60a, 60b, that is, downstream of a brake fluid, such as a slave cylinder 16 (S2). Then, while the slave cylinder 16 is caused to perform a stroke operation by the transmission of a command from the instruction device to the ECU 101, the worker bleeds air in the downstream of the master cut valves 60a, 60b (S3). |
