Booth to proportioning valve was leaking so I replaced it then try to bleed the system but no matter how many times I bled them I still have no pedal so does that mean that I need to replaced my proportion ing valve need help. I have priced new valve and it is about 300.00 from dealer.

 

Poor connection or a bad bleeder valve allowing air to be drawn in.

You can go to a manual valve there should be quite a few threads on doing that.

 

you can take them apart .. it is a valve with a plunger ... kind of like a 'slave cylinder" on a clutch ..
It may just be stuck in 1 position ..

I would try free it up first
