A pneumatic brake pedal module for a brake-by-wire brake system of a vehicle is disclosed. The brake pedal module includes a pivotably mounted brake pedal and a damping unit. The damping unit is mechanically coupled to the brake pedal to generate a resistance when the brake pedal is actuated. The damping unit comprises a housing and a piston, which is mounted movably in the housing and divides an internal space of the housing into a pressure chamber and a vacuum chamber. The pressure chamber and the vacuum chamber are connected to one another in terms of flow. The piston has on its running surface an encircling annular space in which a ring seal is accommodated in an axially movable manner. The ring seal is located at least in a flow path between the pressure chamber and the vacuum chamber and forms a restrictor in the at least one flow path, which restrictor frees different flow cross sections in the at least one flow path depending on the axial direction of movement, and damps the movement of the piston with differing degrees of strength depending on a direction of movement of the piston.
