Abstract: A vehicle brake includes a disk that is rotationally integral with a central drum of a wheel, which is rotatingly supported on a shaft and forms a half-shell of a two half-shell housing compartment. A cover half-shell is provided opposite the central drum and is rotatingly unsupported with respect to the central drum, and has a braking element compressible by a pushing member against the facing surface of the disk. The disk includes a crown of teeth or radial ribs engaging a concentric crown of recesses on the central drum, which has a backing surface of at least part of the radial teeth or ribs and at least part of the face of the disk facing the drum. The backing surface provides the countercheck of the disk against the compressing action of a braking element against the surface of the opposite disk face.
