Dude, I feel your pain. mine went out 2 weeks ago just before our New Years Day run. If fluid level is up you can try and bleed the slave cylinder to see if it somehow got air into the lines, if not, replace the slave cylinder first and then re-bleed, if not that, replace the Master cylinder. That's got to fix it as there is nothing more to the damn things. Be careful of aftermarket slave cylinders. I got mine at Autozone and it was defective. I had replaced both the slave and the master cylinders, bled the system and still no go. I then got an Isuzu Slave cylinder, replaced it, bled it out and whalaa, it works great. I hope it is not as cold where you are as it is in Utah, it hurts to breathe here. Good luck..
