slave cylinder bleed help?

[leesredgt]

ok at first we got all the air out we put a tube in a bottle so it would not suck any air back in,but the pedal will still not come back up it just goes to the floor,so then we took the slave cylinder off the transmission to see if the cylinder is pushing all the way out and of course it is and the pedal will still build NO pressure,i replaced the master clutch cylinder so is my slave cylinder bad now?i mean its pushing all the way out with no leaks around it or anything?plz any help would be appreciated and yes before u flame ive searched and found nothing...thanks in advance

[Joe]

you took the slave off the transmission then put the clutch to the floor?

you probably need a new slave. thats a sure fire way to ruin one. trust me, ive done it on 3 occasions.....

never EVER EVER disconnect the slave and push the clutch pedal.

[leesredgt]

so how would it ruin it if the pedal goes to the floor i mean i just eased it down there and then it wont come back up.how did u bleed ur rb when u had it?is there any other slave i could use like from a 300zx or somthing/will the ka24de rebuild kit work on mine or can i pull the insides out of the ka24det slave that i have and put them in there.i really dont want to have to buy one from mckinney if i dont have to.

Of course the pedal wont come back up without it being bolted to the trans, thats what provides the pressure to push the pedal back.

Do some searching on the net, someone found a slave thats a close match for the rb25det trans.

If you have a 20 trans use the KA slave.

Don't do it again! You basically ruined the seals.

theres a 25 slave rebuild writeup on racebread.com in the FAQ section.

What kamin means is, you cannot put the clutch to the floor when the slave isn't connected to the trans because the piston will shoot out of the slave.

you can disconnect it from the trans IF every time you put the pedal down you open the bleeder too, but usually i just leave it on the trans and to bleed it

[leesredgt]

so what happenes if my piston didnt come out all the way?and when we connect back it will not push the fork in enough to push the pedal back up it builds some pressure but not no were near not even close to what it should be i mean even before we took it oof it wouldnt push the pedal back...

[Joe]

it will probably leak once you build pressure in the system. or shortly after.

You will also have to adjust the master slave under the dash. Once it does bleed up your not going to have a full pedal until you adjust the foot pedal. Only takes a second.

[leesredgt]

how can u ajust the pedal i mean i know what your talking about b/c i had to put a new master slave on but how can you adjust the pedal anymore i thought it had to be were it was originally and if u adjust it wont it pull the pedal in?

[thenillaz]

I'm pretty confused as to what all this talk about pistons falling out and such(don't know much about RB trans), but to help with the original bleeding question, lets just say you didn't fnck anything up and never took the cylinder off the car, I know s13s have another bleed screw on the chassis if you follow the plumbing. Should be on a square block looking thing a foot or two down the line from the slave, forget what is it. Also make sure all the line screws are tight throughout the plumbing.

REMOVE THAT GAY DAMPER LINE IF YOU HAVE IT

just disconnect it and gently bend the hardline to reach

i ****ing hate that thing.

[thenillaz]

You refering to the thing I'm talking about?

[Joe]

yes, its called a clutch damper line. its made for women who have a hard time controlling their left foot and dont like harsh engagements.

with an aftermarket clutch it makes the pedal feel spongy and can cause engagement/disengagement issues.

[ryan15]

Stainless braided line FTW, I just gravity bled it with this line. only clutch ive been able to bleed like this!

what the hell is a "master slave"? the part is either a master or a slave

God your a car guy and you don't know what a "master slave" is?

Its the slave in charge of all the other slaves... head slave if you will.

He obviously meant master CYL.

one man brake bleeder..

fill it half way up with fluid, connect it to the slave, open it up, fill the master up, pump the clutch with your hand... empty the bottle 2 times, and fill up the main thing about 3 times and you will be done in 2 to 5 minutes :-)

This works very well actually.

And if it fails use a pressure bleeder and be done in like 1 min.

[leesredgt]

ok we took out the box and metal lines that are right before the slave and you know what after that i pumped the clutch twice and instanley built pressure now it works fine.thanks guys

[Acecool]

Dont forget to top off the master.
