I have asked this question previously but didn't precipitate any information regarding the single line air brake; information about modern systems is not relevant.
I have a trailer which is czech army. It has Single Line airbrakes; there is no immediate reason why these shouldn't work as intended with a little attention.
Could any body point me in the direction of some information on this system? Which I assume would be Eastern Bloc. standard for the '60s era.
Anyway as I remember from experiences with a Praga a while back; the service brakes on this worked in a pressure to apply the brakes fashion; that is non fail safe. They did fail regularly due to leaks various.
The trailer has a reservoir in the system; which would suggest brakes would come on when the line pressure in the single line dropped in a fail safe; railway brakes fashion.
However I would like to use the trailer with a tractor with Two Line trailer brakes. Any thoughts on how this might be achieved? This isn't my field really. It is obvious that neither of the lines of the two line set up will alone operate the single line system using the service brake pedal as would be desirable and if I am going to make it work I might as well get it to work properly; having a separate trailer brake valve would be only a halfway improvement.
I have found a couple of companies that seem to offer a "braking system" kit mainly for upgrading agricultural trailers that have hydraulic trailer braking to suit modern tractors that now have air brakes; they also do air brake modules to fit on tractors with only hydraulic trailer braking so there is air braking provided sensed from the hydraulic brake system.
