Beschreibung
Zusammenfassung:	The present invention improves the durability of a diaphragm in a configuration where a suction valve provided with the diaphragm is provided. This vehicle brake hydraulic pressure control device is provided with a suction valve (6) disposed between a master cylinder (M) and the suction inlet of a pair of pumps (5a, 5b), wherein the suction valve (6) can be opened by a pressure difference between the brake hydraulic pressure on the master cylinder (M) side and the brake hydraulic pressure on the suction inlet side which becomes negative pressure under the actions of the pumps (5a, 5b). Each of the pumps (5a, 5b) is provided with a plunger, a suction valve, and a discharge valve. The pumps (5a, 5b) can discharge a brake liquid to a flow passage connected with the master cylinder (M) and a wheel brake (R), and are configured such that the discharge cycles of the brake liquid are different from each other by half a cycle.
