A master cylinder arrangement (10) for a vehicle hydraulic brake system has a housing (14) and a bore (16), which is formed in said housing along an axis (A) and in which at least one filling chamber (18) and a first pressure chamber (22) are delimited. A filling piston (38) and a first pressure piston (40) connected thereto displace fluid from the filling chamber (18) to the suction side of a hydraulic pump (60), the discharge end of which delivers pumped fluid into a first brake circuit (64), and from the first pressure chamber (22) into the first brake circuit (64). To realize a desired, so-called "entry behaviour", the filling piston (38) and the first pressure piston (40) are movable relative to one another by a limited amount (s) along the axis (A). Furthermore, the filling piston (38) and the first pressure piston (40) are spring-biased in relation to one another in such a way that they are pushed apart from one another, and the filling piston (38) couples rigidly to the first pressure piston (40) after both pistons (38, 40) have been moved relative to one another by the amount (s) counter to the spring force pushing them apart from one another.
