This paper analyses reliability of the pneumatic system of “Karosa” buses in the PSC “Vilniaus Autobusai”. A search of structural solutions is carried out for improvement of reliability of weakest units of this system. The work includes a statistically processed fault distribution and laws of such distributions are determined. The main fault reasons are enumerated. At last, solutions of problems of improvement of the pneumatic system are presented. It was established, that the unfailability indications of compressors, made by “Knorr” manufactory, can be increased by alignment of the safety valve so, that it would open at pressure 1.1 – 1.25 MPa. At the same time it will increase and reliability indications of valves located in the high pressure part of this system.
