Abstract: The invention relates to an electrohydraulic brake release device (1) comprising an actuating cylinder arrangement (400), a tank module (300) for receiving a hydraulic medium, an electric drive unit (200) and a functional unit (100) having a pump assembly (113). The pump assembly (113) is arranged in a recess (111) provided in the functional unit (100), which recess is in communication with the tank module (300), is functionally connected to the actuating cylinder arrangement (400) by way of a conduit arrangement (150, 160, 170, 171, 172, 180, 190) and by way of a bearing carrier cover (115) is sealed off from a dry-running drive motor (210, 211) of the electric drive unit (200). The invention further relates to a brake system comprising a brake release device of this kind.

Abstract: The invention relates to a functional unit (100) for a brake release device, comprising a recess (111) for receiving a pump assembly (113), an actuating cylinder support (119) for receiving an actuating cylinder arrangement (400), wherein the functional unit (100) is formed as an integral functional block where the actuating cylinder support (119), the recess (111) and a plurality of channels (150, 160, 170, 171, 172, 180, 190) for a hydraulic medium are developed, said channels forming a line arrangement. The invention also relates to a brake release device having such a functional unit.
