A pair of diaphragms (34,36) divide a housing cavity into several chambers (38,40,42). Fluid pressure supply to the chambers is controlled by a valve assembly (50) movably contained by the housing (32). The housing and valve assembly cooperate to define an output pressure chamber (70). - During brake application, one diaphragm is movable oppositely to the valve assembly to generate fluid pressure in the output chamber. Such pressure biases the valve assembly to move. The housing is connected to a master cylinder (16).
