A disc cover for disc brakes on a two-wheeled vehicle having a series of fan elements attached to a wheel attaching axis and adapted to be nested in a stored configuration or overlapping and covering the disc when deployed. The elements are attached to each other when deployed and are all locked together when nested by an attaching pin. Each element is in the shape of a U or L such that the outer surface projects over the disc surface but the inwardly turned portion extends only part way about the disc.
