Abstract
A brake booster mechanism comprising a casing, one or more pressure responsive power walls in the casing, valve mechanism associated with the power wall and being movable relative thereto to control the differential pressure across the power wall, an actuating member connecting the pedal for manually moving the valve mechanism, an output member for connecting the power wall to a brake master piston, a brake feel reaction member having a compressive member interposed between the actuating member and the output member with a play clearance with respect to the actuating member in the retracted position of the booster mechanism, and adjusting thread member for regulating the play clearance whereby during initial stage movement of the actuating member is opposed by no brake reaction force through the compressive member until the actuating member becomes in abutment against the compressive member past the clearance.
