Abstract: There is provided a brake system that can generate a desired braking force in a nondefective system even if at least a secondary side system of a tandem master cylinder is defective. When the secondary side system is defective, a primary piston (assist member) is moved by a larger amount than an amount of movement of an input piston (input member). Pressure in the nondefective primary side system is increased, and this can compensate for a braking force for two wheels on the primary side, which may be reduced by the defect in the secondary side if no measure is taken, and allows a desired braking force to be generated. Further, the pressure in the primary side system is increased to apply hydraulic pressure reaction to the input piston and an input rod (input member), thereby achieving good pedal feeling.
