Another useful thing to have when troubleshooting is my CJ-6 Air System

Yes, the brake reducing valve is in the upper right of the cut-away drawing
I sent you.=C2- The other two components are the brake disabling solendo
id (lower right) and the brake differential valve (left side).
When you said "no one seems to have kits right now", I'm assuming you did c
heck with Doug Sapp, the CJ parts supplier?

Thanks Dennis, so this is the reducing valve?=C2- You had said the reduci
ng valve was in the upper right of your picture, and this is in the lower r
ight, so just confirming before I buy a replacement (noone seems to have ki
ts right now).

I think my leaking part may be the brake disabling valve?? It looks like the figure
in the lower right, has one line coming in, one line going out, and an open
unused male fitting (where the leak originates). It also has the little hangy
down part like in the lower right figure. I included a picture of the part
in the prior post, but it is kinda blurry.

If it's coming from the brake disabling solenoid, which by the way I
have never seen in over 18 years, fabricate yourself a bypass by
connecting the "goes-in" line to the "goes-out" lineand remove the brake
disabling solenoid from the aircraft. Secure the cannon plug when
removing it from the solenoid.

Thanks Dennis. The disabling valve is already disabled from being active, so I'm
guessing that may be why the port is unused (maybe not, I have no idea how it
was disabled). It'd be nice if I could just cap that port.
I know it'd be safer to bypass/remove the whole thing. What is the best option
for the short piece of line and 2 fittings that I'd need? Is there a source for
aluminum line, or would copper or something like that work?? Sorry if this is
a dumb question.

Dennis/Bmsim,
An out of the kits to o/h the QS1 (brake pressure reducing valve) at tis

Doug,
I think Bmsim said he believes the leak is coming from the brake
disabling solenoid, which is between the brake reducing valve and the
brake differential valve. If that's where the leak is coming from, it
would be a first for me, since the only way the brake disabling solenoid
dumps air pressure overboard is if it is activated, thus preventing air
pressure from reaching the brake differential valve (QS2 on the CJ).
If it ends up not being the brake disabling solenoid, then most
definitely he should purchase the new brake reducing valve (QS2) from you.

That is correct, it is just purging air out that open port.
Thanks for the valuable info Dennis, very much appreciated!
Doug, if it turns out to be something else I'll definitely purchase the replacement
from you.
Thank you!

What you may want to try first is disconnect the cannon plug on the
brake disabling solenoid and see if the problem still exists when you
squeeze the brake handle. If it does, proceed with the bypass.
