I just downloaded the service manual and checked it out.  Do you have a copy?  I'd be happy to send it to you via email.  It does say and show how to bleed the delay valve.  There is a bleed fitting on the delay valve you have to bleed it just like the calipers.

I just made a vacuum bleeder out of a reynolds handi vacuum packer. It is working great 20 lbs of vacuum and it is making bleediing the brakes so much easier

Whatever works!  It shouldn't be very difficult to bleed them via pumping the lever.  The way I do it is to pull off the resevoir cap, attach a tube and bleed bottle to the caliper nipple.  Then loosen the nipple, pump the lever without releasing it, close the nipple and release the lever.  Repeat until there is no air coming out the line.  Be sure not to let the reservoir run empty.

Arkie, haven't you bled everything there is to bleed?  Maybe you have a faulty master cylinder on that side?  Sure hope you get it fixed soon.  I know you want to RIDE!  And we all want to know what the final solution is.  I guess I'm out of ideas right now.  Good luck !!!

Way cool Arkie. So it all came down to air in the line?

And the cause of the wheel locking up?

I have had a similar problem this weekend only the front brack of the combination brakes it would not bleed other than a small trickle..back brake no problem squirted out. I wasnt getting air out i intended to change the fluid on a 24000k service . Did nt do the balance valve as I reasoned  the brakes would bleed  if I didnt do it as the balance cylinder would be full before and after bleeding only the after condition  would have fresh fluid in it and  both brakes should bleed fluid as they were both connected to the same reservoir, however as I say the front one wouldnt ...any clues folks? is it something to do with the action of the balance cyclinder not moving and letting fluid to the front brake..the manual does not say how this cylinderr operates...I always presumed that while  the pressure was below a certain level the back one would work then the balance piston would move when the pressure rose enough and then allowed the front to work?

I believe it works the same as a proportion valve in any car on the road. The valve itself (ballbearing)  simply floats against a spring. I would think the bleeder is on the valve due to the limited flow it can handle. I have not seen the manual on this one but I would think you must bleed the line to the valve first, then bleed the remaining line to the wheel.       .I always presumed that while  the pressure was below a certain level the back one would work then the balance piston would move when the pressure rose enough and then allowed the front to work?   I believe this statement is correct.

I've got the manual if you'd like me to email it to you?  I haven't read the whole thing but it does have a nice step by step on the bleeding procedure.  You have to bleed the valve.
