Duel booster break system trouble shooting

Wade R


Hello who's ever eyes land upon this. I seem to be having trouble finding anyone who might have knowledge pertaining to the dual booster break system that is on my 1981 gmc  B6000. This isn't the hydro-max nor the hy-power this is the dual power booster system that has a vacuum booster attached to the firewall followed by what I have found to be called the power head which is essentially a hydro booster but unlike the hydro booster it cannot be taken apart to replace the seals and O-rings.That is then attached to the MC. Any litterateur or knowledge one might have would be greatly appreciated!!! As of now I have found one picture of my exact system and it is a drawing from a catalog. Yet to find any literature anywhereScreenshot_20200615-000744.thumb.png.2dfa51d03d95a1ddb7e7131464b15051.png
