The invention relates to a method for adapting the brake cylinder pressure (pc,<SUB>actual</SUB>; pc<SUB>1</SUB>/pc<SUB>2</SUB>/pc<SUB>3</SUB>/pc<SUB>4</SUB>) of a pneumatic brake of a rail vehicle (FZG). According to the invention, during a braking process, the momentary actual slip (s<SUB>actual</SUB>) between at least one wheel ( 2 ) of the rail vehicle (FZG) and a rail ( 3 ) is determined, a desired slip (s<SUB>desired</SUB>) between the at least one wheel ( 2 ) and the rail ( 3 ) is predetermined, and the brake cylinder pressure (pc,<SUB>actual</SUB>; pc<SUB>1</SUB>, pc<SUB>2</SUB>/pc<SUB>3</SUB>, pc<SUB>4</SUB>), which corresponds to the difference of the actual slip (s<SUB>actual</SUB>) from the predetermined actual slip (s<SUB>desired</SUB>), is modified such that the difference between the desired and actual slip is approximately zero or is at a minimum. The desired slip can be, selectively, in the micro or macro slip range. A braking state factor is determined in the event of a stable braking process, from axle speed measurements and brake cylinder pressures.
