The brake system for a rail vehicle comprises a pneumatic or hydraulic pressure medium source and a brake actuator for converting an input pressure into a brake force which is exerted on at least one wheel. Also provided is a brake force transducer which, during the exertion of the braking force, is subjected to the corresponding tangential force. According to the invention, the brake force transducer generates, as a result of the action of said tangential force, a control force, a control travel or a pneumatic or hydraulic control pressure. Into the working line between the pressure medium source and the brake actuator there is connected a regulating valve which is additionally acted on by the control force or the control pressure. The regulating valve changes the exertion of pressure on the brake actuator such that the control force or the control pressure is kept below a set limit value. The limit value corresponds to full utilization of the adhesion limit at the wheel contact point. It has been identified that, in this way, most uncertainties in the transfer function between the pressure in the brake actuator and the exerted brake force can be eliminated, such that it can be ensured that the adhesion limit is not exceeded. In particular, no fluctuations in the efficiency of the brake actuator have to be taken into consideration.
