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?

did you make sure you cleaned out the return hole from inside the resevior? this prevents a vaccuum so the fluid can flow.

its really tiny and hard to see.

another trick is to bind your brake lever to the handle bars overnight to let the fluid enter the seals.
