The invention provides a vehicle brake apparatus. In individual flow passageways (51) connecting a main flow passageway (52) connected to an accumulator (32) of a power fluid pressure generation device (30) with wheel cylinders (42), holding valves (61) are disposed. The holding valves (61) permit communication between an upstream side and a downstream side in an open valve state to transmit a fluid pressure from the accumulator (32) to the wheel cylinders (42), while disconnecting the upstream side and the downstream side in a closed valve state. Of the holding valves (61), the holding valves (61RR, 61RL) disposed in left and right rear-wheel brake systems in which the fluid pressure on the main flow passageway (52) side (upstream side) to which the fluid pressure is transmitted from the accumulator (32) is not less than the fluid pressure on the wheel cylinder (42) side (downstream side) at all times are provided with check valves (CV1, CV2) in parallel for reducing the fluid pressure of the wheel cylinders (42) by permitting communication only from the downstream side to the upstream side.
