Re: Help problem with brakes!
more likely than not it's the front rubber flex lines . old ones can/will collapse internally , then act as check valves . it's common with older vechicles , i have had it happen to myself several times . it's not only G.M. vechicles , i had it happen to my 1989 dodge p/u . i have owned my truck since new . many others on this site will confirm . replace them , good luck .

rubber flex lines
"Collapse" isn't exactly what they do, but the effect is about the same... they rust internally, and eventually completely close off the little tiny hole through the fitting.
Just change em out, and then go from there.
