Abstract: A normally engaged torque transmitting device is disclosed. In a typical application, the device is used as a brake to resist rotation of a shaft. The device consists of two members normally frictionally clamped together by one or more sets of interleaved friction discs and separator plates such as those commonly associated with shaft connecting clutches. The first member is a cylindrical housing with means for attachment to a shaft, stationary frame member, or the like. The housing includes a bore in which is received at least one friction disc splined thereto to permit axial but not rotational movement with respect thereto. The second member is a collar for fixed connection to a shaft or the like and includes outwardly extending separator plates interleaved with the friction discs on the housing. The friction discs splined to the housing and separator plates splined to the collar are urged into engagement by a pressure plate and spring means. A tubular member is carried within and engages the pressure plate. Two spaced annular plates are carried between the housing and tubular member. Introduction of fluid in the space between the annular plates separate the plates and, via the tubular member, moves the pressure plate away from the friction discs and separator plates.
