GREASES FOR BRAKE COMPONENTS. TESTS WITH BRAKE CYLINDER LUBRICANTS AT THE VIENNA ARSENAL TESTING STATION

Several Administrations have reported that the brake equipment fitted to their rolling stock does not function correctly under certain conditions, due to incorrect lubrication. Without considering the effect of moisture, Committee E 18e was asked to study the question, and decided firstly to deal with brake cylinder lubrication. A working programme was approved at the same time and this envisaged two stages of work- 1st stage- Tests at the Vienna Arsenal Vehicle Testing Station, using a variety of greases on a number of cylinders. 2nd stage Line tests using the grease which had given the best performance in stage 1, in the coldest part of Europe. This report contains the results of the 1st stage of the programme of work and describes tests carried out using a number of greases with six brake cylinders at low and ambient temperatures. It also explains why the Committee does not intend to pursue the 2nd stage of the programme of work. By interchanging the greases in the six cylinders chosen, it has been shown that failure of the brake cylinders at low temperatures is not due to any special grease composition (as far as those greases tested are concerned). The general conception of the brake cylinder unit seems to play a more predominant role - primarily the quality of the rubber cups and secondly, the form of the cups and the roughness of the inner surface of the cylinder. As a result of the committee's work, a possible specification for a brake cylinder lubricant has been drawn up and is given in Appendix 1. Its purposes is as a guide for the Administrations in choosing a suitable lubricant.
