Default Clutch is acting funny (as in expense funny)

South Bend (Con OFE) clutch has almost 100k on it and the last few trips with it the pedal goes somewhat limp and even though it's pushed to the floor, it acts as if I'm letting it out slowly. If it's in gear, it wants to take off. It's random, but it's starting to do it more often. I checked the hydro line from the little fluid tank all the way to where it goes into the clutch housing and no issues there. Any ideas?

Might be you got a little air in the line. Try and bleed it, and if it's a no go, might be the clutch master cylinder went out.

How do I bleed that line? And where is the master cylinder? Sure would like to fix this without digging into the clutch. I'm about 1000 miles from home (where my truck sits) and will be home weekend after next for just two days, but if I had some leads on what to look at while I'm there that would be helpful, thanks!

The master cylinder will be on the firewall, under the brake master cylinder. The bleeder will be on the actuator which is on the fork, on the bell housing (front of the transmission).

Master cylinder and slave were both bad. New ones fixed it. Now just need to wear out a leg to pump all the air out.
