A brake booster assembly and method of operation thereof are provided. The assembly includes a rack moveable along a first axis. A sensor is coupled with the rack for sensing force and displacement of the rack and outputting a proportional signal. A clutch subassembly is disposed adjacent and coupled to the rack and includes a drum and a hub in a spaced relationship with the drum. A motor is disposed adjacent the rack and coupled to the clutch subassembly for rotating the drum. A magnetorheological fluid is disposed between the drum and the hub. An electromagnet is disposed about the clutch subassembly for generating an electromagnetic field to affect the viscosity of the magnetorheological fluid. A controller is electrically connected to the electromagnet and to the sensor and to the motor for controlling the motor and the electromagnetic field of the electromagnet in response to the signal from the sensor.
