Bleeding Clutch???

I replaced my master cylinder yesterday, now I have no pressure in the pedal. I searched everywhere I could find to get help. Heck, I eve called Scott from this board.

I guess the first question I should ask is what does the bleeder screw look like and where is it? On my slave cylinder, all I have is one "port" that has a screw in in, but it's a hex head plug type screw. I don't have a zerk fitting that I could put vacuum pump on to help (like you would do with brakes). I went and got a new slave cylinder today and it didn't come with anything in that port, but was told by the Autozone folks that I just replaced it with what is my current slave cylinder.

My haynes manual states that i should remove the dust cap that fits over the bleeder screw, but I don't even know where that is. The picture that it shows I can't locate on my Jeep.

Any and all help (as quick as possible) will be greatly appreciated.

Thanks,
Kevin

the hex head plug is the bleeder on the slave cylinder

Mine was rusted too bad so I bought a new slave. If your replacing the entire slave, leave the plastic "compressor" on the slave when you instal it. the pressure once you bleed it will snap it into location.

Then how in the Hell do you bleed the system then? And, can you use something like a Mityvac (and if so, how). I can't seem to get mine to bleed. I cannot ever get the clutch to build enough pressure. I bought a new slave today, but don't want to install it if I don't have to. What's the "compressor" that you are talking about?

Thanks,
Kevin

You bleed it the same way you bleed brakes.

Unscrew bleeder valve
press clutch to floor and hold
tighten bleeder valve
release clutch
repeat until no more air comes out

And after each cycle be sure to check the fluid in the resevouir

I've tried that until I am blue in the face. Been through about 2 bottles of brake fluid. How far open do you turn the bleeder valve?

You only need it a 1/4 turn to allow fluid to come out.

Now you're going through fluid but nothing is coming out? of the peddle simply isn't gaining any pressure?

Going through fluid and plenty is coming out. I can't get any pressure on the clutch pedal.

Hmm, thats odd, and you're following my instructions? I'm just tryingto figure out whats going on.

Try pumping the clutch really fast and see if you can build up pressure, you should get something whether theres air or fluid in the lines. if you don't then theres a leak somewhere

Is the "bleed screw" in yours like I described above? A "plug type" allen screw.

I've got a 98 TJ. If I had what you have, it wouldn't be a problem as I could hook up my vacuum pump to it. Reckon you could buy just those fittings?

According to this you can't bleed the TJ clutch

I've never heard of a self bleeding clutch

Bleeding my Clutch on my 98 TJ?? - JeepsUnlimited.com Forums

Now I'm confused

Unless it works somehow like this

Sounds like an awesome idea...except for the fact that I can't get it in gear and drive it anywhere...

Guys at the NAPA in Moab suggested rapidly tapping the clutch pedal without depressing it. The vibration shakes the air bubbles loose and they float to the top. It does work.

Take the lid of the MC and you can see the bubbles rising from inside the cab. . . while you're doing the tap dance

This issue is why some decide to bite the bullet and pay an arm and a leg for the master, slave, and plastic line in one piece.

Yeah, hindsight 20/20, I shoulda just done the whole thing. I have been doing some other reading as well, and this is a thought...

Unscrew the slave from the tranny housing and pump the piston 100 or so times and have someone keep an eye on the reservoir and keep filling wiht fluid.

Think this will work?

You'll still have whatever air is down in the slave. Go ahead and try the tap dance. You could be on the road in ten minutes.

Guess the MOAB NAPA guy knows what he is talking about. I tap danced on the pedal about 150 or so strokes. Then, I started pumping the actual pedal all the way to the floor about 25 times. Noticed there was a bit of pressure building up and did it about 25 more and it's fine now. I'll be taking that new master cylinder back now I guess.

Thanks to all for all the help (especially TJ2 and Vaultzz)!

Glad you got 'er put back together. It's a job that was frustrating for me too. It's one of those jobs where the next time you do it, will only take 15 min.

I'd keep the master... IF you were losing pressure in the petal the master is the culprit. Only special tool you need for that is a pin punch. I forget the size but trust me it's worth 5$.
