Vehicle brake system

A vehicle brake system comprising:

• a control unit capable of determining whether a transmission is set in a driving mode, in which a power outputted by a power unit of a vehicle is transmitted to driving wheels, or in a non-driving mode other than the driving mode;
• and
• a booster unit for increasing a braking force generated when a brake operation unit is operated,
• the vehicle brake system being configured to be able to operate a braking force holding function for holding the braking force which is generated by operating the brake operation unit,
• wherein the control unit operates the braking force holding function when the braking force is applied and a speed of the vehicle becomes lower than a predetermined speed threshold value, and
• when the control unit operates the braking force holding function and determines that the transmission is set in the non-driving mode, the control unit increases the braking force, which is generated by operating the brake operation unit, by the booster unit and holds the braking force.
