i just did mine everything new including a dual resevoir m/c on the frame, combination valve,residuals,and a pressure brake line switch, all new lines and hoses ,wheel cyclinders,calipers,cut ,bent and flared where needed....bench bleed the master then hooked up a little vaccum pump to the farthest away wheel cyclinder and started pumping ......did not know a brake system could leak in all those places

most just needed a good tightening but one of my flares needed a little filing....all in all for my first complete job i was pleased...but that vaccum pump was the cats a##........dave
