My 92 F-250 is loosing brake fluid. No sign of it on the drums or wheels. Could it be bypassing the master cylinder and ingested in the vacuum pump?

Break the two nuts loose on the MC and pull it forward some, don't have to pull the brake lines off if you're only moving it that small distance. If it's leaking by it you should be able to tell from there.

If its filling the booster up with brake fluid the booster will fail soon. Thats why they offer a master and booster as a set. I caught my jeep filling the booster and i flooded it with water to try to save it. That was a few yrs ago, i got lucky.
