If you plan on rebuilding the wheel cylinders first take a bleeder wrench and see if you can get them to back out without breaking off. If they break off, toss them and go new. Same with your steel lines. If your budget allows, go all new hydrulic parts and make sure your hardware is safe. Unless you have a lot of free time on your hands, rebuilding master and wheel cylinders is almost a wash,cost wise. Where are you in NE PA?
Thanks to all for the advice. I will see if I can get the bleeder valves to back out and go from there with the wheel cylinders. Plan on replacing all the lines.
Mike, I live in Mountatintop, just south of Wilkes-Barre
