摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a brake hose 10 which prevents an outer skin rubber layer from being partially swollen and which exhibits excellent productivity.SOLUTION: A method for manufacturing a brake hose 10 includes an inner pipe rubber forming step of extrusion-forming a rubber tube body 12A to form an inner tube rubber layer 12, a braiding step of manufacturing a hose-braided body 12C by forming a splicing yarn layer 13 on the rubber tube body 12A, and an outer skin rubber forming step of covering the top of the hose-braided body 12C with an outer skin rubber material to form an outer skin rubber layer 20. In the outer skin rubber forming step, the hose-braided body 12C is heated so that a temperature Th of a surface of the hose-braided body 12C is raised to 50°C or more, and an upper surface of the hose-braided body 12C is covered with the outer skin rubber material under an atmosphere in which a pressure is set at 0.8 or below with respect to an atmospheric pressure in an area for covering the hose-braided body 12C and outer skin rubber material.
