The invention relates to a master brake cylinder arrangement for a hydraulic motor vehicle brake system having a housing, in which two adjacent cylinder bores are provided, two piston arrangements, in which a first piston arrangement is received in a first cylinder bore of the cylinder bores such that it is displaceable along a first longitudinal bore axis and in which a second piston arrangement is received in a second cylinder bore of the cylinder bores such that it is displaceable along a second longitudinal bore axis, a force input piston which can be coupled, or is coupled, to a brake pedal and which is displaceably guided along an actuating axis in a cutout of the housing, the first piston arrangement and the second piston arrangement being displaceable according to a movement of the force input piston, in which the first piston arrangement delimits a first pressure chamber with the housing, said pressure chamber being fluidically connected to a hydraulic brake system, and in which the second piston arrangement delimits a second pressure chamber with the housing, said pressure chamber being fluidically connected to the hydraulic brake system. It is provided that, arranged between the first piston arrangement and the second piston arrangement and the force input piston, there is a transmission element on which a coupling projection is mounted, which is connected, or can be connected, in force-transmitting manner to the force input piston for common movement.
