An adjustable pressure simulator device for vehicle braking systems of the brake-by-wire type may have an absorber body enclosing a first cylinder and a second cylinder fluidically communicating with each other and at least partially filled with a fluid. The first cylinder houses a first piston subject to the thrust action of the fluid and biased by a first elastic device which opposes the thrust action applied by the fluid. The second cylinder houses a second piston subject to the thrust action of the fluid and biased by a second elastic device which opposes the thrust action applied by the fluid. The first and the second elastic devices have different rigidities so as to induce the displacement of the second piston only after having reached a predetermined stroke of the first piston, under the thrust action of said fluid.
