A brake pressure control unit of vehicle load responsive type is disposed in a brake pressure line extending from a master cylinder to wheel brake cylinders and composed of a P-valve, a load-sensing lever abutting on a plunger of the P-valve, a secondary spring disposed between the bracket secured to the P-valve and the free end of the lever, and a primary spring disposed between the other free end of the lever and a lower end of a rod which is swingably held on the other free end of the lever. The brake pressure control unit is preassembled as one unit before it is installed in the vehicle as it is. The direction of the biasing force of the secondary spring is the same as that of the primary spring.
