The invention discloses an automobile brake vacuum tube. The automobile brake vacuum tube comprises a first hose, a second hose, a third hose, a fourth hose, a fifth hose, a first three-way connector and a second three-way connector. A vacuum tube port is formed in one end of the first hose, and the other end of the first hose is connected with the first three-way connector. A connector is arranged at one end of the second hose, and the other end of the second hose is connected with the first three-way connector. The left end of the first three-way connector is connected with the third hose, the third hose is further connected with the second three-way connector, the other two ends of the second three-way connector are connected with the fourth hose and the fifth hose respectively, an inlet manifold port is formed in the other end of the fourth hose, and a first one-way valve is arranged in the fourth hose. A vacuum pump port is formed in the other end of the fifth hose, and a second one-way valve is arranged in the fifth hose. According to the automobile brake vacuum tube, on the premise that the requirement for the vacuum degree of a vacuum booster is met, the vacuum degree of the engine inlet manifold is effectively used, and the working intensity of a vacuum pump is reduced.
