A brake master cylinder arrangement includes a housing with a cylindrical recess, a pressure piston moveable in the cylindrical recess along a longitudinal axis and guided in a sealing manner, and a reservoir for storing brake fluid that is fluidically connected via a fluid channel to the housing. The pressure piston and the housing enclose a pressure chamber that is connected to a fluid circuit of the brake system. Depending on the position of the associated pressure piston, the pressure chamber is either fluidically connected to the fluid reservoir or disconnected therefrom. In a region that axially spans the sealing arrangement in a starting position of the pressure piston, the outer circumferential surface of the pressure piston has profiling that provides a fluidic connection between the fluid reservoir and the pressure chamber.
