Abstract: The present invention comprises: a first pressure-regulating mechanism that pressurizes a first wheel cylinder on either the left or right front wheel side of a vehicle, by using the movement of a first control piston driven by a first electric motor; a second pressure-regulating mechanism that pressurizes a second wheel cylinder on the other side, out of the left and right front wheels, by using the movement of a second control piston driven by a second electric motor; an opening/closing means interposed in a connection fluid path that connects the first wheel cylinder and the second wheel cylinder; and a control means. If the operation amount for a braking operation member is less than a prescribed value, the control means puts the opening/closing means in a connected state, puts the first electric motor in an electricity-supplied state, and puts the second electric motor in a non-electricity-supplied state.

Abstract: The present invention comprises: a first wheel cylinder on either the left or right front wheel side of a vehicle; a second wheel cylinder on the other side; a first pressure-regulating mechanism that pressurizes the brake fluid inside the first wheel cylinder; a second pressure-regulating mechanism that pressurizes brake fluid inside the second wheel cylinder; and a normally-closed opening/closing means interposed in a connecting fluid path connecting the first wheel cylinder and the second wheel cylinder control means: determines whether or not the operation of a brake operation member is a sudden operation; and, if a sudden operation is determined, puts the opening/closing means in a connected state and, by using the first and second pressure-regulating mechanisms, increases the pressure of the brake fluid inside the first and second wheel cylinders.

Abstract: Brake fluid inside a first wheel cylinder is pressurized by using a first pressure-regulating mechanism and brake fluid inside a second wheel cylinder is pressurized by using a second pressure-regulating mechanism. If a determination means determines that the first pressure-regulating mechanism action is in an unsuitable state and the second pressure-regulating mechanism action is in a suitable state, the control means pressurizes the brake fluid inside the first wheel cylinder by using a master cylinder and pressurizes the brake fluid inside the second wheel cylinder by using the second pressure-regulating mechanism, when an operation volume is less than a value. When the operation volume has reached the value, the control means pressurizes the brake fluid inside the first and second wheel cylinders by using the second pressure-regulating mechanism.
