I found the QS-1 overhaul kit to be a fairly difficult exercise. Buy the co
mplete assembly and fly with a known good unit.

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).

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.=C3=AF=C2=C2=BD If it does, proceed with the by
pass.

Yak 52
I took the bypass valve out. The bypass button/solenoid was disabled years ago,
but evidently something inside has failed, allowing air to escape via the open
port when the parking brake is applied.
After removing the valve, there is plenty of line to bend it over and eliminate
the bypass valve if I had a male/male union. Does anyone know where I might be
able to get a male/male flare union that I could plug in after putting the appropriate
angle on the line? I'm having trouble locating this part so far.
Thanks Guys,
Brandon

Sounds like the one I have. The headset works very well, but you definitely have
to put a helmet and ear cups on over it in a Yak.

Be careful trying to bend the original tubing. It is very brittle and
can easily crack.
You could try Doug Sapp for the male to male union. But I can honestly
say I have never seen one (metric with the correct flare).
The alternative is what I described earlier using the 5052 metric
aluminum tubing.

Thanks Dennis, I shot Doug a note.
Do you know where the differential valve is located? The line from the pressure
reducing valve into the disabling valve is easy to see/replace, but the line
on the other side of the disabling valve disappears as it heads to the differential
valve. I'm not sure if it is nearby or I'm looking at a long complex run
of line to replace it.

Yes, it's on the forward side of the front spar on the right side of the
front seat. Look down from the seat on the right and you'll see the
swing arm which moves fore and aft when you move the rudder pedals. The
swing arm is mounted to the brake differential valve. If you follow the
air line forward from the brake disabling solenoid, it is attached to
the rear of the brake differential valve.
(Now you know one of the reasons why I still teach the 2 day Yak 52
maintenance training course)

Does anyone have available a Baklan 5 that they wish to sell? Mine is not
working and I do not know where to have it repaired. I am after the main bo
