Hello all
I have a mercedes 612d vario that im doing up ready for an expedition, there is an annoying problem that i havent got to the bottom of yet. For 6 months now the truck has been taking lots of time to build air pressure (air over hydraulic), this has got worse and will now not build enough air pressure to release handbrake, the air cylinder light on dashboard will not go off and the brakes are on (not completely but i can feel them on). There are no audible air leaks in the system. The air compressor is turning over and the first tank has pressure, the second tank does not seem to have any pressure, i realised this by pulling the cords to bleed system, first tank releases as it should, second tank there is no air at all, i guess the second tank is fed by the first. Does anybody have any experience of this? or any suggestions as to what I could try next? thanks
