The invention relates to a method for decelerating a vehicle train with a traction vehicle and at least one trailer vehicle with an anti-lock brake system, and to a combination of pneumatic brake systems of the vehicles of a vehicle train. In order to improve the braking behaviour of a vehicle train, the invention provides that an electronic brake control unit (30) of the traction vehicle brake system (3) detects a current vehicle deceleration actual value (z-lst), continuously compares the vehicle deceleration actual value (z-lst) with a maximum deceleration (z-Max) and in the event of the vehicle deceleration actual value (z-lst) reaching or exceeding the maximum deceleration (z-Max) limits the brake pressure (P) and makes available an information signal (45) for the respective brake electronics (31) of each trailer vehicle (6), which information signal (45) represents at least one piece of limiting status information (46), - wherein the respective brake electronics (31) of a trailer brake system (4) - acquire measurement signals (35) from rotational speed sensors (34), and set the brake pressure (P-A) at the wheel brakes (13) as a function of the measurement signals (34) by actuating pressure control valves (27) - receive (52) the information signal (45), and, when limitation (44) of the brake pressure in the traction vehicle (5) is detected on the basis of the measurement signals (34) for each trailer axle (11, 12), determine a dynamic slip variable value (v, vRA) which represents the slip, - compare (49) slip variable values (v, vRA) of all the trailer axles (11, 12) with one another, and close the inlet valves (32) of the respective pressure control valves (27) at least at those trailer axles (12) with the higher slip values than a control axle (11) and the currently lowest slip.
