No clutch....Help

I pulled into Walmart empty last night and when I went to leave I had no clutch or clutch brake. I ended up shutting the engine off, starting it in second and floating the gears all the way to a truckstop.

I'm going to head home during the night and have my mechanic fix it but am curious what it could be.

I'm guessing it's not anything to do with the linkage. I have full pressure on the pedal like my clutch is fine. I think if it was anything to do with the linkage I wouldn't have any pressure on the pedal at all? I just talked to my mechanic and he thinks it's probably the throwout bearing?

No, I didn't have a clutch problem. Years ago I had my clutched replaced. I recently posted about that taking around 4 hours to replace with 3 guys in a pit and $2,500

 

I'm in Hubbard, OH at the Flying J and will head out tonight back to NH. Just a few toll stops but other then that it will be smooth sailing.....I HOPE!!!

 

That has actually happened in the last few months!!!! I had no clutch brake then all of a sudden it was back again.

 

If it's not one thing it's another. Just had a ton of trailer work done. My brakes were dragging. Turned out to be the relay valve like @Cat sdp pointed out. New air tanks, 2 drums and 2 brake kits. That resulted in an IFTA quarter with 3.8mpg. Then pneumonia that kicked my ### for 12 days a few weeks ago.
