I disconnected the brake rod from the M.C. First,,it was then I Found the M.C. was not stuck, and I was able to determine that the hydrovac rod was stuck, accumulation of rust on the steel rod caused it to seize up, after getting it unstuck, I hooked the brake pedal back up and the hydrovac unit was moving, the brake pedal going thru the normal motion,, so hoping after the M.C. is rebuilt I will have brakes,, time will tell.
