The present invention relates to a master cylinder arrangement for a motor vehicle hydraulic brake system comprising a housing, in which two adjacent cylinder bores are provided, two piston arrangements, wherein a first piston arrangement is received in a first of the cylinder bores so as to be displaceable along a first bore longitudinal axis and wherein a second piston arrangement is received in a second of the cylinder bores so as to be displaceable along a second bore longitudinal axis, a force input piston, which is connectable or connected to a brake pedal, wherein in accordance with a movement of the force input piston the first piston arrangement and the second piston arrangement are displaceable, wherein the first piston arrangement with the housing delimits a first pressure chamber, which is fluidically connected to a hydraulic brake system, and wherein the second piston arrangement with the housing delimits a second pressure chamber, which is fluidically connected to the hydraulic brake system. In this master cylinder arrangement it is provided that between the first piston arrangement as well as the second piston arrangement and the force input piston a separate transmission element is disposed, which is movable into joint abutment with the first piston arrangement and the second piston arrangement.
