摘要：
The invention relates to a primary piston assembly (22, 28) for a master brake cylinder (12) of a vehicle braking system with a first primary piston component (22) having a first piston element (24), to which a driver's braking force (Fb) is transferrable in such manner that a pressure chamber volume of a pressure chamber (10) of a master brake cylinder (12) of the braking system that is fillable with a liquid can be reduced by displacement of the first piston element (24) via the driver's braking force (Fb), wherein the pressure chamber volume that is fillable with a liquid can be further reduced by means of a first braking support force (Fu1) provided by a braking force amplifier actuator device (26), and wherein the primary piston assembly (22, 28) comprises a second primary piston component (28) with a second piston element (30), to which the first braking support force (Fu1) is transferrable in such manner that the pressure chamber volume of the pressure chamber (10) can be reduced by displacement of the second piston element (30) by means of the first braking support force (Fu1). The invention further relates to a production method for a braking unit with at least one master brake cylinder (12) and one braking force amplifier device (48), and a method for operating a braking unit.
