I'm trying to rebuild the front MC on my 78 XS 400 and cannot get it to bleed. What am I missing? I rebuilt the caliper. I claned the MC bore. Installed the rebuild kit as the old parts came out, and can't get it to bleed. After 4 hours of dickering with I am to ready to throw this bike in the dumpster. I since pulled the banjo bolt off the MC, and can't get fluid out even there. I even tried a vacum bleeder and nothing. Any help?
