Clutch MC or Slave

[Jimjordan2]

I have a 67 Series V, the New Clutch MC and New Slave Cyl. now have 6500 miles on them. Using standard whatever # fluid. After sitting for about two months while I was installing the new dash, the clutch would operate only with the pedal all the way to the floor. Plenty of fluid, No leaks. I vacuum bled the Slave Cyl and operated just fine for about a month. Again, pedal to the floor. I'm sure it will work once I bleed it again, but that's not the fix.
Would I suspect one over the other, or just put a new kit in both of them?
Whatcha think guys?

Hm, hydraulics are usually a leak or air problem. I would go through the system carefully for those items again, with some tests while actuating the system (things somethimes leak or suck in air as they are moving) - The one other question I would ask is if the cylinder bores of MC and slave are properly ratioed.

I just re-did my clutch hydraulics this year.
Just my thoughts, not my field of expertise, hope to learn from others here.

Are you having to add fluid ?

Dan, Only after I've vacuum bled the system. But no fluid loss otherwise.
