An object of the present invention is to decrease the machining cost and to improve the productivity. A liquid pressure control device (21) for load responding brake comprises a valve mechanism (25), which is slidably disposed in a housing (22), for decreasing the liquid pressure of a master cylinder in a predetermined proportion and transmitting the liquid pressure to a rear wheel brake cylinder by the movement of a plunger (24) operated in response to the liquid pressure from the master cylinder; and a load sensing mechanism (27) in which a load depending on the movable load of a vehicle is applied to the plunger (24) so as to move the pressure decrease operation start point of the valve mechanism (25). The housing (22) is formed by cutting a long material (50) formed by extrusion or drawing to a predetermined length and then by machining the cut material (51).
