the other day I was out trail riding and went through a really deep mudhole and noticed my clutch kept getting stiffer and stiffer throughout the day. I pulled the slave cylinder out and cleaned all the mud out behind the fork, didnt help any, the pedal would still not push in at all, took the master cylinder off, it still pumps, and im gonna take the slave cylinder off and see whats up with that. Anyone had this problem? I have to get my truck ready for this weekend. I'm wondering if the slave cylinder locked up or something.

Check for a kinked line going to your slave.

Do you have a 'full' bellhousing with the lower steel front plate? May be packed in below

I have gotten crap stuck in the fingers of the pressure plate before. Real pain in the ass. Had to take the clutch out and clean all the crap.
