Dumb question.... but i've seen customers replace brake parts... i.e. calipers and brought to our shop for your same exact reason and seen that the calipers were on the wrong side and bleeders were at the bottom side of caliper. just an idea

lol, I know what you r saying, but no the bleeders r on the top.

Does it stil have r.a.b.s. module valve under drivers seat frame rail? if so, i seen them "stick" after power bleeding. only available at j yards or maybe ebay. i've tapped with a hammer before and gotten them unstuck. just an idea

Haven't seen this mentioned. What vacuum are you you reading? PB booster will require minimum 12hg to work properly. Not familiar with your cam, some produce low vacuum. A vacuum canister can be added for reserve if thats the problem. I'm a little concerned on my present build, but won't know till I fire it up.

I would say that your booster is not the problem. If it fails, the pedal would be hard. The job of the booster is to reduce pedal effort when running. Since the pedal is soft when running, I would rule out the booster.

See if you can find someone with a reverse bleeder. I've had to do this on postal trucks.
