In an automatic boot mounting method or an apparatus for practicing the method, a wheel cylinder is held at a predetermined position, and a boot is mounted on the tapered shaft portion of an inserter. The small-diameter shaft portion of the inserter is held with an inserter moving device with the large-diameter shaft portion of the inserter faced to the cylinder body. With the inserter set along the central axis of the cylinder body, the boot is moved to the large-diameter shaft portion of the inserter by a guide plate. The inserter is moved along the central axis of the cylinder body by the inserter moving device until the end face of the large-diameter shaft portion abuts against the end face of the protrusion end portion of the piston. A first air supplying device supplies air into the boot, to inflate the boot, to fit the large-diameter sealing portion of the boot in a seal groove formed in the cylinder body, and a second air supplying device supplies air into the hydraulic pressure chamber in the cylinder body, to move the piston thereby to fit the small-diameter sealing portion of the boot in a sealing groove formed in the piston. Thus, the large-diameter sealing portion and the small-diameter sealing portion of the boot can automatically be fitted in the sealing grooves formed in the cylinder body and the piston.
