ok guys,
The front brakes are jacked, I have adjusted till I am blue in the face, so I tore it all apart, removed everything, the pistons are froze/rusted in there cylinders, I cleaned them and soaked them in PB blaster, still I can not get them the budge. so...
can they be rebuilt? replaced? disc brake conversion.

remember cost is of grave concern, this is a flip.

You can try removing the brake lines and screw a grease zerk into each seized cylinder, then pump the pistons out using a grease gun. Or you can take the cylinders off and boil them in water to expand the aluminum, breaking the expanded corrosion bonds. Once you get them apart you'll probably need to pick the corrosion out of the pits in the cylinders with a sharp dental pick, scuff the bores up with a scotchbrite pad and fill pits with JB-weld before sanding the excess epoxy back down flush with the bores. If you do that, let the JB-weld (original formula only) cure for a minimum of 48 hours at room temp before exposing them to brake fluid.

Thanks retro, I tried the grease gun trick, it did get one of three out. I think they are just to far gone to save. I will try to remember that trick in the future.
I think since these are not the original brake shoes (have water grooves) someone put the shoes on, and didn't replace the cylinders, these shoes look really good and so does the springs, I dout they ever worked correctly. I am going to just replace the cylinders and pray for the best. the drums look ok , I have already replaced the upper hose/line I hope this gets me some brakes. Pictures coming soon.

FYI- be careful when you order chemicals off of Amazon- there is a NO return policy for anything type chemical paint/cleaners/solvents/etc.

you wasn't holding your mouth right on using the grease gun trick !, i've done it this way for many years, not once have I never got all the pistons out of the bores on the wheel cylinders !!. grease in a grease gun has a ton of psi pressure, nothing comes close other than hydraulic fluid ?. do it again, unless your not applying enough pressure on the grease gun ?, I see no reason why it wont push the pistons out !!!. oh, and you must close off the other hole in order to get the grease to push them out !.
