I used to deal with this a lot. Remove all four wheel cylinders and the master, completely dissassemble each of them and inspect the rubber parts for failure or wear. Clean everything with denatured alcohol and then plug the ends of the lines and fill them with denatured alcohol, and let that sit in the lines for a couple of days. Pull the stopper out at the ends and blow compressed air through the lines. If anything looks jakey in the wheel cylinders or master replace it, between the Raybestos and Wagner catalogues you can get new cylinders. If you get new cylinders, take them apart and clean the parts with denatured alcohol then coat them with whatever fluid you are going to run the system on. Same with the master. Put everything back together and bleed. One thing I really like abut the new wheel cylinders is that they use steel pistons now and the old problems with electroysis is no longer possible.
