    摘要： The present invention obtains a vehicle brake system capable of suppressing a cost increase.
    A vehicle brake system 10 according to the present invention is a vehicle brake system 10 including: a hydraulic pressure control unit 6 controlling a braking force generated to a vehicle 1; a first master chamber (first master cylinder 21a) that is a master chamber for a front wheel 2 and at least communicates with a wheel cylinder 24 of the front wheel 2 of the vehicle 1; and a second master chamber (second master cylinder 21b) that is a master chamber for a rear wheel 3 and at least communicates with a wheel cylinder 26 of the rear wheel 3 of the vehicle 1. The hydraulic pressure control unit 6 controls a braking force generated on one wheel of the front wheel 2 and the rear wheel 3, the first master chamber and the second master chamber is connected to the hydraulic pressure control unit 6, and, of the first master chamber and the second master chamber, the master chamber for the other wheel of the front wheel 2 and the rear wheel 3 is connected to the wheel cylinder of the other wheel without the hydraulic pressure control unit 6 being interposed therebetween.
