Hydroboost help

[turboclam]

I have replaced......... hydroboost, master cylinder, proportioning valve, calipers. Brakes seem to bleed OK. The pedal feels good until I start the car. Pedal almost goes to the floor when engine running. What is the proper way to bleed this setup and am I missing something? Thanks

How old is the booster and lines? Are there any leaks? Is the power steering pump in good shape? If there are any shavings that have come from the steering gearbox to the booster that is a killer. I run an in line filter in the hose between the gearbox and the reservoir to keep any possible shavings out.
Anyway these are just some ideas.

Did you bleed the master cylinder first before bleeding the rest of the system ?

Thanks Wrath! I did not bleed master cylinder before installing on car. Oops. I figured that I would bleed it out by the pedal. I will bleed it again. Thanks, Michael
