Pump kit for spring applied hydraulic release brake

Abstract

A pump kit includes a motor assembly including a first spline as an output, the first spline being coupled with a second spline of an actuator shaft; the actuator shaft including an extension with male threading threaded with an inner female threading of a piston within a through hole of the piston; and the piston including an external slot with a component having an at least partial spherical surface sitting therein, the component having the at least partial spherical surface also being partly positioned within a hole within an outside of a housing; where the slot, the component having the at least partial spherical surface, and the hole in the housing are configured to prevent the piston from rotating in an operational configuration, such that the operational configuration instead includes the piston moving toward a fluid cavity within the housing.
