Thank you all for all the good advice,now i got to get to work.

also is it recommended during reassembly to use some tyye of sealer,gasket maker on the gaskets

thats probably it!!the new cup that was in my rebuild kit for the large air piston is why its so tight,looks like leather or something similar and very stiff,any ideas in how to make it more plyable?

I did lube well,deciding to get another rebuild kit and try again,try to reuse what i have ,or soak it up and buy a new airpak.what a headache!!

i had to give the big piston a good tug with visegrips attached to get it out of the can,i did hone the cans bore ,it looked good before and still does,the new cup made it tight,the only other threaded hole in the airpak ,besides bleeder is a thin hex plug kinda under the bleeder that reveales...

where would the second bleeder be located?i have the oid type airpak.

carefully inspected the bore of small air piston and there is some pitting there that i didnt catch before,may be the problem,i imagine even light pitting couldnt be good,not super bad but cant be honed smooth

no,just one bleeder,i have tore down on my bench now looking for the problem,the large piston in can is very hard to move ,should it be that tight?i remember it was hard to get started during the rebuild, and what did you use to hone the small air valve piston bore?

Anybody have the understanding of how these airpaks work that may point me to a specific part,piece to look at as to why its not releasing the fluid back to the m/c?

you are referring to the piston cup and the pushrod seal?

I also would like to tkank everybody as well,i disassembled most of my airpak while still on the truck just to see if everything was in place and didnt find anything abnormal,lubed it a bit while apart and put it back together,now its raining and have to wait to see if anything changed

yes,can crack that fitting in the airpak and frees them up

No ,bleeder does nothing,if i crack the fluid line at airpak it will release,makes me think its not a line at axles

checked plug and no air,pedal after repeated pumping gets very stiff,running out of things to consider,although i noticed when driving and it does this it seems to affect the rear wheels first,there again ,new hoses ,blew out lines, shoes adj properly ,i dunno

All new rubber lines,i tried that over the weekend,thought one may be twisted,but all look good.

ok,started up,built pressure,pumped brakes enough times to lock up,jumped out with truck running and cracked the driver side glad hand and NO AIR!!! comes out ?? air will come out pass side glad hand though

Fired it up,let air pressure build up,shut it down ,pulled plug in can and no pressure there,the brakes were locked last nt and this morning they're free.but as always a short drive will lock them again

Yep,caught that one ,just wandering if the springs kinked or something during reassembly

What part of the airpak controls fluid pressure ?I mean if i were to disassemble it again what parts need to come off to see why it went release pressure back to m/c? hopefully i wont have to take it completely apart.

Yes i did,thought it went well.
