Abstract: An axially split brake disk that includes two brake bands that form a brake ring and are interconnected by ribs. The brake disk further includes two brake ring halves that are separated by concentric and radially extending seams of division, in each of which one of the brake ring halves is provided with a projection that extends in a concentric direction, while the other brake ring half is provided with a corresponding U-shaped recess that accommodates the projection. The width of the projection is less than the width of the brake ring, as measured in a radial direction. The projection of the one brake ring half, as well as that portion of the other brake ring half in which the recess is provided, are provided with corresponding radially extending bores for receiving a holding mechanism, such as a sleeve-like or rod-like member, that is provided with pin-like elements for preventing the holding mechanism from shifting in a radial direction relative to the brake ring halves.
