Brake system bleeding 78 911sc

I have searched for specific answer to my question, but find it difficult to find information on bleeding a dry brake system with power bleeder.

My 1978 sc Targa sat idle for 10 or more years. I have managed, with help of Tony, to get the thing running well. Now I want to make sure it will stop.

I decided to take the safe route and disassemble, clean, replace major components including brake master cylinder (replaced,) inspect brake booster, Calipers (rebuild,) and lines between body and calipers (replaced.) I have purchased the Schwaben power bleed from Pelican and am progressing toward getting everything back together. No major problems so far............I think I may have dodged a very expensive bullet on the brake booster: master cylinder may have been leaking as some paint on the booster was badly bubbled. Inspection of booster revealed no internal corrosion. I guess I will find out for sure, shortly.

My question is whether or not there are any considerations- not applicable to normal brake system bleeding/flushing- associated with refilling and bleeding a dry brake system with a power bleeder. All the information on power/pressure bleeding I am able to find has to do with bleeding and flushing a systems that is already full of brake fluid.

Any advise is appreciated.

Best,

Wayne
