Abstract: PURPOSE: To avoid the phenomena to have the generated pressure increased more than the determined rate in such a way that conduction of a replenishing chamber to a reservoir is cut off in response to the generated pressure, and the piston is locked.  
     CONSTITUTION: The small diametral part of a stepped piston 5 generates braking oil pressure, and a large diametral part 4 forms a replenishing chamber 7. The replenishing chamber 7 conducts to a reservoir 12 through a valve which is constituted by a piston 17 and a seal 16. The piston 17 can slide in a chamber communicating with pressure chamber A, B, and move in response to the generated pressure,  and when the generated pressure comes up to the determined upper limit, it closes  the valves 17, 16 to cut off the replenishing chamber 7 from the reservoir 12. Thus,  the piston 5 is locked, the generated pressure does not rise more than the upper  limit, and any excessive pressure does not work to each part of the brake.
