A wheel axle (18) of a rail vehicle is provided with an electro-dynamic brake system (33) and with a not fully rated mechanical braking system (22). A braking method for braking the wheel comprises at least a service braking mode carried out solely with the electro-dynamic braking system (33), a parking brake mode carried out solely by the mechanical braking system (22), and an emergency braking mode comprising a first level emergency braking mode carried out solely by the electro-dynamic braking system (33) and a second level emergency braking mode activated when the first level emergency braking mode has a malfunction and carried out solely by the electro-dynamic braking system (33) as long as a low efficiency condition of the electro-dynamic braking system is not met and at least partly by the mechanical braking system (22) when the low efficiency condition of the electro-dynamic braking system (33) is met.
