Claim 0:
1. A vehicle braking device provided with a hydraulic circuit having a first system, a second system, and a connection flow channel connecting the first system and the second system, comprising:
a fluid supply unit configured to supply fluid to the first system;
a first braking unit configured to apply a braking force to a first wheel by using the fluid flowing in the first system;
a second braking unit configured to apply a braking force to a second wheel by using the fluid flowing in the second system;
a determination unit configured to determine whether the fluid is leaking from the second system;
a control unit configured to execute specific control for controlling the fluid supply unit so that an amount of fluid supplied to the first system is increased in response to determination by the determination unit that the fluid is leaking from the second system; and
a master cylinder having a cylinder and a piston arranged slidably inside the cylinder, and an input chamber and an output chamber defined by the piston are formed in the cylinder,
wherein the connection flow channel is connected to the input chamber,
the second system is connected to the output chamber, and
the control unit configured to execute the specific control until a volume of the output chamber becomes the minimum in response to the determination.
