PURPOSE: To facilitate manufacture by a method wherein a storing chamber and a damping chamber are arranged on the extension of a valve receiving means, in a device provided in a single block with a valve receiving means to receive control valves, a pump receiving means, the storing chamber, and the damping chamber. CONSTITUTION: A pressure control device for a double circuit brake device is provided with a valve housing 10 formed in a single block, and a normally- opening first control valve 12 and a normally-closed second control valve 22 operated by electromagnets 16 and 26 are located at the valve receiving bodies 14 and 24, respectively, in the valve housing 10 and respectively arranged at two brake circuits, Further, two return pumps 42 in the valve housing 10 are disposed orthogonally to the axis of an electric motor 32 and facing each other in a radial direction, and each pump 42 is arranged in a pump receiving means 44. Through the operation of each pump 42, fluid in the storing chamber 54 formed on the same axis as that of the valve receiving body 24 is pressurized and discharged through the damping chamber 64 formed on the same axis as that of the valve receiving body 14.
