The invention discloses a vacuum assisted hydraulic brake system which comprises a first service brake operating mechanism, a second service brake operating mechanism, a brake dividing valve and a brake assisting pump. The vacuum assisted hydraulic brake system can realize braking by operating the first service brake operating mechanism, can also realize braking by operating the second service brake operating mechanism, and can also realize braking by simultaneously operating the first service brake operating mechanism and the second service brake operating mechanism. When a first brake pedal and/or a second brake pedal are/is trodden, the brake dividing valve can be driven to push the piston motion of the brake assisting pump, further the brake assisting pump moves forwards, a brake disc of the second service brake operating mechanism carries out braking, and therefore a tourist coach is braked. The vacuum assisted hydraulic brake system can realize bi-directional braking, and therefore the safe hidden trouble of a bi-directional tourist coach is reduced to some extent.
