Abstract
A brake fluid pressure control device including a power pump provided in a fluid supply line for discharging fluid into the main fluid line. An on-off valve is provided in the main fluid line upstream of the point at which the outlet circuit of the pump merges with the main fluid line. A fluid reservoir is provided in the fluid supply line upstream of the pump. For automatic braking, a changeover valve is changed over to supply fluid in the first chamber into the inlet port of the pump. When the automatic braking is off, the inlet and outlet ports of the pump are connected to the second and first chambers of the reservoir, respectively, to supply fluid into the first chamber.
