A controller (140) receives a brake command (B), and in response thereto controls electrically operated brake units to apply respective brake forces to respective rotating members (111, 112, 113, 114) being mechanically linked to the wheels (121a, 121b, 122a, 122b, 123a, 123b, 124a, 124b) of a rail vehicle (100) to reduce its speed. The controller (140) repeatedly checks if each brake unit fulfills an operability criterion and is faultless (OK), or does not fulfil the operability criterion and is faulty (F). The controller (140) also repeatedly determines an adhesion parameter reflecting a friction coefficient between at least one wheel (121a, 121b) and at least one rail (191, 192) upon which the rail vehicle (100) travels; estimates, based on the adhesion parameter, if it is possible to increase a respective brake force of each of the faultless (OK) brake units (172, 173, 174) to compensate for any faulty (F) brake units (171), and if so, in response to the brake command (B), controls the faultless (OK) brake units to apply a respective brake force to the respective rotating members, which respective brake force is increased to compensate for any faulty brake units.
