ーキ装置。A hydraulic pump 6 is operated by a spring force and released by hydraulic pressure acting on the brake chamber 4, and is connected to the brake chamber 4 via a filter valve, a brake valve 10, and a relief valve located downstream of the filter valve. Furthermore, in a hydraulic release type brake device in which a bypass valve 12 is connected in parallel with the filter 7, there is a communication position 9a between the filter 7 and the brake valve 10, and a drain for draining pressure oil on the brake valve 10 side. A switching valve 9 is installed, which has a position 9b and is biased toward the drain position 9b by a spring force, and is biased toward the communication position 9a by pilot pressure from the circuit pressure. A hydraulic release type brake device characterized by:
