Claims

[Scope of utility model registration request]

Built-in first and second pistons that simultaneously generate primary hydraulic pressure and secondary hydraulic pressure to be supplied to the wheel cylinder side of the front wheel brake device when the first bushing rod is pushed in by the brake pedal. a first mask cylinder; an actuating cylinder having a piston driven by the secondary hydraulic pressure of the first mask cylinder; A pressure chamber is connected to a pressure chamber, and when the brake is not applied, both the first and second pressure chambers are maintained at an equal pressure state, and as the operating rod connected to the piston of the actuating trigger moves, the first pressure chamber and the second pressure chamber are maintained at an equal pressure state. a master back that drives the power piston by the pressure difference between the first and second pressure chambers when atmospheric air is introduced into the second pressure chamber; and a second master back that is connected to the power piston of the master back. A second mask cylinder has a built-in piston that generates hydraulic pressure to be supplied to the wheel cylinder side of the rear wheel brake device when pushed by the bushing rod, and is connected to the vacuum mechanism and responds to the load of the loaded vehicle. and a vacuum pressure adjustment mechanism for adjusting the vacuum pressure in the first pressure chamber of the mask back.
