An adhesion estimating device (2) for a brake system (1) of a rail vehicle having brakes (3', 3", 3"', 3"") that can individually brake wheelsets of the rail vehicle is provided. The adhesion estimating device (2) comprises a braking demand distributing unit (4) for redistributing an overall braking demand into individual braking demands, wherein the braking demand distributing unit (4) redistributes the overall braking demand requested for a predetermined deceleration into different individual braking demands such that the individual braking demands result in the predetermined deceleration, and an evaluation unit (7) determining a correlation, between a current adhesion value allocated to a current individual braking demand, and a current slip of a wheel braked by the one of the brakes (3', 3", 3"', 3"") for estimating an adhesion value between the wheel and the rail.
