today driving to school my clutch lost all resistance and just hit the floor so i got a ride home towed back to the house now it's seized and wont go down any one got any ideas of what is might be
thxs for all the help guys
-
Check your linkage where the pedals connects to slave at the firewall, also check fluid level.
-
the master used to go every year or so on ym YJ. it would do just that, start to feel odd then poof, seize solid, then drop right off. odds are its in the master/slave hydraulic system.

When my master went a couple years ago there was fluid leaking at the firewall where the linkage goes through, that would be one easy check. The fix was easy but a bit expensive. I bought the entire "closed" system from the stealership since they don't sell the master/slave separate. I am sure there are ways around that though.

so i finally got it in my garage i checked the flood-id it was really low so filled it up and now it still stiff
is it a fully hydraulic clutch and is there a way to bleed it or something?

If it's anything like the Ford's hydraulic setup....replace it while you have the chance. If it's low, then there is a leak in the system somewhere and it's just going to happen again. With the system being low, it's not releasing the clutch properly and thus causing the blocker rings and synchro's in the transmission to wear faster than necessary. On the Ford's there is a way to bleed them, although with the design of the master cylinder and the way it's mounted, you would ideally need to pick up the front end of the truck off the ground about 3-4' in order to get all the air out of the system. This is why the Ford's were notorious for bad clutches... I'm not sure about the style of the jeeps though....
Mine is doing this right now, and I've got parts coming in this week. New clutch, master & slave cylinders, and I'm still trying to find a flywheel, but I may just buy a new one to make it easy....
*EDIT* I believe this is what the slave cylinder looks like if I found the right part. It looks like you are able to bleed the clutch, although I still recommend that it be replaced because of the leak.
