Abstract
A brake booster is provided with a housing (30) having a bore (32) therein receiving a piston (52) carrying a valve assembly (68). An end plug (50) cooperates with the piston (52) to form a work chamber (66) and an input member (84) extends through the end plug to cooperate with the valve assembly (68). In the rest position, the work chamber (66) communicates with a reservoir (38) via passage 112, auxiliary chamber 104, passage 116, bore 32 and passage (40) independently of the piston (52).
