Suddenly dead clutch pedal?

Clutch pedal had been working perfectly for the year I’ve had the truck, have checked clutch reservoir fluid level but have not needed to add any fluid in that time.

A couple days ago as I was slowing for a stop sign there was a bit of a squeal from the transmission area and then when I pressed the clutch pedal I could tell it had much less resistance than normal. I took off from the stop and on the 1-2 shift the clutch pedal went to the floor and gave me nothing. I had to rev match to get home. When I got home I checked fluid levels and the clutch fluid was still full. The pedal is dead until maybe the last 1/2” of travel on the floor.

My guess is slave cylinder, but I’m no hydraulic clutch expert. Does anyone have any suggestions?

Sounds that way to me. For that age I would plan on a whole clutch job, with all new hydraulics. Buy pre-bled.

Try bleeding the system and see if you can build pressure in the pedal. If not, probably a bad slave cylinder.
