Driving down Ohio turnpike when I exit I have no clutch, The pedal is on the floor, Push truck through Toll booth, Open hood and check master cylinder oil level its full. Pump clutch pedal and it comes all the way up to full clutch, Drove 100 more miles and made it home. Next day went out to move truck and pedal was froze in normal up state, Stood on clutch pedal with 2 feet and it still would not move. Now I cannot start cause clutch needs to be depressed to start. Called AAA and had towed to a garage, They replaced the master cylinder and the slave cylinder now it works fine.
