PROBLEM TO BE SOLVED: To improve brake operation feeling in a vehicle brake system without a pressurization assistance mechanism.SOLUTION: An elastic member 12 elastically deformable in a range in which the moving of a brake pedal 11 can be sensed is provided between the brake pedal 11 and a M/C 13. With this configuration, even if the depression of the brake pedal 11 stops at a predetermined position and then the brake pedal 11 is to be additionally depressed, the deformation of the elastic member 12 enables the depression of the brake pedal 11. As a result, the pressurization by a brake-fluid-pressure control actuator 50 is switched from a pressure holding state to a pressure increase state, the stroke of master pistons 13a and 13b can be carried out, and it is possible to prevent a driver from feeling degradation of brake operation feeling. |
