The paper deals with the proposal of new maintenance system of air brake system on a semitrailer combination. The structure of semi-trailer and the current maintenance system of trailers are described with focus on the basic air brake system design. Analysis of wear and damage of air brake system components used on the semi-trailer combination based on real experience from practice and creation of the FMECA analysis of the system using software support are presented. Based on the analysis performed, a new system of maintenance was designed which was aimed at reduction of the risk related to failure consequences. The proposed system uses RPN (risk priority number) values resulting from the proposed preventive maintenance system and is compared with the currentmaintenance system. Main objective was to reduce the impact of any failure in any component on the air brake system. On the basis of the analysis subsequently new methods of failures detection of air brake system components, preventive measures, and suggested new intervals of preventive maintenance for the air brake system are also proposed. Proposed intervals of preventive maintenance execution are based on the calculation of the total costs associated with the consequences of failuresthat may arise from them and compared with costs associated with service inspections carried out on the analysed semi-trailer fleet. The proposed maintenance system has decreased RPN values in comparison with the current system and in practical operation is expected to increase safety of semitrailer combinations, thus minimize probability of a failure in any component of the air brake system.
