A plunger-type booster brake pump equipped with a one-way valve includes a housing assembly and a plunger assembly. The plunger assembly includes a plunger, a plunger sleeve, and a cup. One end of the plunger sleeve is movably disposed within the inner cavity of the housing assembly, forming a first volume chamber between the plunger sleeve and the inner cavity of the housing assembly.
