A brake disc for an axle of a truck of a railway vehicle comprises a brake disc annular element mounted on a hub by a plurality of clamping sleeves seated in radially opposed bores in the hub and annular element. In the regions of the clamping sleeves the hub or annular element is provided with circumferentially spaced lugs which are received in circumferentially extending grooves in radial extensions on the other of the hub or annular element. Radial recesses are provided on the other of the hub or annular element between the clamping sleeves to accommodate the lugs in an axial direction when assembling the annular element upon the hub.
