Jay,
What is "that valve"? Are you talking about the brake reducing valve
that is under the floor in the rear cockpit on the right side? (Yak
52). When you had the "selector valve" out, did you put a new overhaul
kit in it? Doug Sapp has overhaul kits for both the brake differential
valve (selector valve) and the brake reducing valve (that valve?). Do
you have any binding in either the front or rear brake cable causing the
brake handle to appear to release very slowly? This is not a common
problem. BTW, is your airplane a 52 or a CJ?
Dennis

Subject: Yak-List: brake problems
Went flying today and when I went to put the plane back in the hanger,
I couldn't. Parking brake was not set, but the wheels were locked up
solid. Did some looking around and discovered I could get the brakes to
release by moving the rudder back and forth. Figured the problem might
be the selector valve. Pulled it out and cleaned it up. No obvious
problems. Put it back in and no change. Then I noticed that when I
squeeze and release the brake lever instead of a quick "phist" of air I
get a slow hiss down by the reducer valve. Well hell, that must be the
problem. Out comes that valve. Cleaned it up (boy was it dirty) and put
it back in. Well, you guessed it, no change. What's up?
Thanks,
Jay

Dennis,
Yes it is a Yak 52. The first valve that I took out and cleaned was the
"selector valve". Did not rebuild it with seals as it looked just fine. The
second valve that I took out was the one under the floor in the right side of
the
rear cockpit. That "reducer valve" was very dirty inside but the seals looked
to be in good condition. As for the brake cable, I will look at that this
morning. It does release very slowly. Thanks for the help.

The kits are about $65 each from Doug. If you don't know when they were
last rebuilt, I would strongly recommend you consider rebuilding them.

Brake cable releasing very slowly sounds like it may be binding at the
attach bracket at the brake reducing valve under the floor in the rear
cockpit.

I think you should get a Yak-50 and have a whole new set of problems! Plus it would
only cost you half to fix it!

Place a straight edge on the "scissor link". Both halves of the scissor
link should be flush with the straight edge when the actuator rod end is
attached.. Remove the keeper on the actuator shaft rod end and rotate the
rod end to mate with the attach point on the scissor link.

Dennis,
Just got back from the airport after working on my Yak all day. You were
right. The problem was the cable itself. A couple of strands had broken and had
gotten wound up in the outer sheath. The return spring down by the reducer
valve was not strong enough to return the handle when you let it go. It just
held the presure in the line. I was able to replace the inner cable and all is
well. Thanks for your help.
As for that Tim Gagnon guy who says I need a 50, why? I can fly yours!
Thanks man.
