for about the past 6 months ive been having some issues with my clutch.all of a sudden one day the clutch almost went all the way to the floor and about a 1/4 way from the bottom was real hard to press the rest of the way.well i bleed it and solved the problem.then several times since then it would do the same thing and a quck bleed would fix it.well today after a 100 pure miles of 75mph highway trip when i got off the interstate it felt like a dump truck clutch it was so hard to push.when i got it home i gravity bleed it for about 10 min and went through about a half a qt of brake fluid to make sure it flushed out good and problem solved.pedal feels real good now.anyway, surely this isnt normal.any ideas on why im having to purge fluid so often.it never seems to have air in it .just seems like the brake fluid is going bad or something

Sounds like you have some junk or dirt in the master or slave cylinder getting caught up in the ports that return fluid. I would check the Master first.
if i keep bleeding it will it solve the problem eventually or do i need to get a new master cylinder.
Tim may be on to something. There are two holes between the bore and the reservoir. The big obvious one, and another very fine one. I would remove the MC, and disassemble it. If the bore looks good, clean it up good. Make sure you can see light through the smaller hole. Buy a rebuild kit, and reassemble it giving everything a good coat of silicone grease such as Sil-Glyde. Fill it, bleed the MC and then the slave cylinder.
If the bore has much pitting in the working area, just pick up a rebuilt one.
Also, check what linkage you have for looseness or binding. It sounds more like a mechanical problem than hydraulic.

well after bleeding a whole qt of brake fluid through this thing after a couple days of good pedal it has gone to crap again.guess ill start gathering the parts for a complete clutch job.if i have to mess with it might as well make it good for another 100k.clutch,pressureplate,slave cyl,throwoutbearing,mastercyl,hyd line from master 2 slave,flywheel,pilot bearing,inputshaft bearing(ive heard this thing rattling for 4 years).can yall think of anything else.
That pretty much sums it up for a complete clutch job. If you replace all of those things I can almost guarantee you wont have any further problems.
The immediate problem seems to be in the hydraulic system.
A rebuilt master cyl, slave cyl, and a bleeding, should get you going again.
If the clutch is not slipping or chattering, you may not need to pull the trans..

I really hate to see you replace the clutch if the problem is in the hydraulic system. One of the first steps in removing the transmission is to remove the slave cylinder. While you have it off, try moving the lever with a wrench. If it seems to move in and out stiffly, but smoothly and quietly, forget the transmission, and work on the hydraulic system.
On the other hand, if it is rough, notchy, or noisy, well at least you have the slave cylinder off already.

my slave cylinder is in the tranny mounted on the input shaft so the tranny has to be pulled anyway.i kind of have a new theory.i checked the trans fluid today and it was a full qt low from when i last changed it and didnt have enough to completely fill it.im just wondering if this caused enough heat around the input shaft area where the slave is located to boil the hyd fluid.seems whenever i bleed the system the fluid always comes out black and its been getting bled about every 3 months for a while now.another observation i made is the hyd line from the master to the slave runs about 6 inches away from the exhaust manifoid.i have an exhaust leak somewhere around the manifoid or the flex pipe.could this be boiling the fluid in the hyd line.seems the problems get worse after a long time on the highway when im turning 3000+rpms for more than an hour at a time.
Definately top off the tranny lube.
Any way you can fabricate a heat shield for the hyd line? Plumbing insulation or something cheap like that? This would assist in isolating the source of the problem.
Hopefully it is not the slave cylinder.

The more posts I read, the less it sounds like a hydraulic problem. Unless something plugs up, or the fluid thickens, it is never going to make the pedal hard to push. That is going to be a mecjhanical problem. Could be at the pedal, or inside the clutch.
What is the line made of? Some of the newer ones are plastic which would never take the temperature to boil the fluid. Boiling could cause a soft or low pedal, but never having the pedal turn heavy half way down.
Changing the fluid because it is black is like changing your oil when it looks black.

Brake/clutch fluid likes to be clean to work right.
