Provided is a brake apparatus and a brake control method capable of improving accuracy of control of a wheel cylinder hydraulic pressure. The brake apparatus includes a first brake circuit connecting a master cylinder configured to generate a brake hydraulic pressure according to a pedal operation and a plurality of wheel cylinders configured to generate a braking force on each of wheels of a vehicle by application of the brake hydraulic pressure to each other, a pump configured to increase a pressure of brake fluid in the master cylinder and transmit the brake fluid having the increased pressure to the plurality of wheel cylinders via a second brake circuit connected to the first brake circuit, a plurality of pressure increase control valves provided in the first brake circuit, and a first target upstream hydraulic pressure calculation portion configured to calculate a target hydraulic pressure in the second brake circuit in such a manner that the target hydraulic pressure exceeds a maximum value of target wheel cylinder hydraulic pressures of respective wheel cylinders corresponding to the individual wheels by an amount of a change in the hydraulic pressure in the second brake circuit when a pressure increase control valve corresponding to a wheel other than a maximum hydraulic pressure wheel, of the plurality of pressure increase control valves, is opened.
