I am looking for a replacement brake valve for my Yak 52. (the green one below the front seat on the right) Does anyone know of a source? The problem appears to be wear in the brake valve cylinders themselves. There is not pitting or scratches, but there are polished areas of wear. Cleaning, lubing, and re-pressurizing and testing the unit reveals no improvement.
Thanks, Mike Cavanagh

Doug Sapp, our CJ6 parts guru has overhaul kits. The assembly you are
talking about is the brake differential valve. The unit in the CJ is
identical to the one in the 52.

Thanks Dennis!  I ordered the overhaul kit from Doug.  On another subject. I have been looking for replacement landing gear bolts and bushings.  Included are pics.  I would like to replace them all.  I 'd need to go count again, but between the main gear and nose there are about 6 or seven I think.  Thanks, Mike [img]cid:inlineImage1[/img]

Jill definitely has the bushings at M14P. I've bought them from her
before. You may not need the bolts since the bolts actually fit inside
the bushings when assembled. Many of the bushing are bronze. So they
will wear long before the bolt wears. Just make sure the hole in the
linkage where the bushing inserts is not worn to the point where the
bushing does not fit snugly into the hole.
