Re: 1958 Packard Hawk brake bleeding

You may have this bit from the 56 Stude shop manual as reprinted in the 57 Packard Clipper supplement. Not much info given in the 58 supplement other than specs but I believe it is essentially an identical layout to the 57.
Since the components are at different heights with convoluted passages in the Hydrovac and the lines go up and back down, I believe they are bleeding in stages starting with the master and line up to and including most of the control section of the Hydrovac. Since the fluid is common to all sections they then bleed the Hydro control section and paths going into power side then finally the power side and lines back down to wheels and the cylinders.
