If it is like all the other dodge/jeep stuff it is not a bleedable system. They come bled as a new assembly and then they have a problem you have to replace the entire setup.
I just bout the truck about one month ago and the dealer just had a mastercylinder put on it and has worked fine till now and I can hold the rod in with my hand when pushing the clutch pedal it must have air in it and just worked its way down
