    • In a brake-pressure producing device of the present invention, a power piston 10 of a hydraulic booster 2 comprises a stepped piston including a large-diameter portion 10a on which fluid pressure of a power chamber 30 is exerted and a small-diameter portion 10b having the same diameter as the master cylinder piston 53. Both the pistons 10, 53 are interlocked with each other through an aligning rod 62. The pressurized fluid of the power chamber 30 is introduced into an annular chamber 51 formed on the circumference of the small-diameter portion 10b and the fluid pressure of the pressurized fluid is exerted on a stepped portion 10c between the large-diameter portion 10a and the small-diameter portion 10b in the direction opposite to the direction of the fluid pressure of the power chamber 30. When the braking operation is performed, the fluid pressure in the power chamber 30 introduced into wheel cylinders 33, 34 relating to one of the circuits and the master cylinder pressure introduced into wheel cylinders 58, 59 relating to the other circuit balance to be equal to each other, thereby uniformly and properly distributing braking forces to the respective wheel cylinders.
