The invention relates to a braking and air suspension system for a trailer, comprises a lifting/lowering valve, supplied with a supply pressure from the supply pressure reservoir of the air suspension system, for modifying the level of the trailer by changing the amount of air in the supporting bellows of the trailer, a trailer brake valve or park-release emergency valve for automatically braking the trailer if the supply line is pulled off, a release valve for neutralizing the automatic braking action when the trailer is unhitched, an actuation valve for a parking brake, a overflow valve via which a supply pressure reservoir for the air suspension system is filled, an air spring valve, supplied with the supply pressure, for adjusting the travelling level of the trailer, an overload protection valve which deaerates the parking brake in proportion to the aeration of the service brake when the parking brake is actuated and the service brake is additionally actuated. The function of the release valve (14') and/or of the actuation valve (13') of the parking brake (11) and/or of the overflow valve (9) and/or of the overload protection valve (12) and/or the function of the automatic braking action when the supply line (parking release emergency valve 3) is pulled off is/are integrated into the lifting/lowering valve (17).
