Bleeding clutch

[Frog]

I am unable to bleed the clutch. When I have someone push the pedal while I open/close the bleeder valve, I have fluid coming out VERY slowly. Pedal never hardens.

I then removed the slave and tried to pump it but had the same. I also had someone push the pedal, while the slave was out. In hindsight, I think I noobed out and might have damaged the slave?.

There is also a tear in the black rubber boot on the master cylinder. Will this cause a leak, or does it not matter?

not sure if the tear will cause a leak, but you can either bench bleed the slave cylinder, or you can leave the bleed screw open and rapidly push the pedal until fluid starts squirting out then bleed it normally from there.

its takes a LONG time to bleed all the air out. and 2 people. pump 5 times, hold down, open valve, bleed out, close valve and repeat. takes me a 1/2 hour to get it just perfect.

You probably ruined the slave. Bleeding the clutch is a headache. Find a Bentley manual!

Perfect example. Oh and by the way there is a Tech section fyi.

I agree too. I did this myself and took over an hour. At first the pedal won't even come off the floor. Just reach down and pull it up.

original slave? might be due for replacement

I used a cheapie vacuum bleeder with the slave dismounted so the screw could point upward. (wasn't that hard)

A $10 vacuum bleeder is a great tool investment.

It was a new slave, how do I check if I damaged it?

Thanks for the input, I will give it another try.

I think you'd have to try pretty hard to damage a new slave.
If you have the original master with a ripped boot - I'd replace it.
One of those deals where the slave and master are worth replacing simultaneously.
(if one goes out - the other is likely to follow)

Frog i damaged my new slave by pumping the master without the slave being mounted in. it causes the internals to expand to far and the little cups pop out and it's trash at that point. u can tell by seeing if the rubber boot has risen and there is a hard metal round cup that is loose.

Be careful pressure bleeding the slave dismounted. you can blow the piston out if you use too much pressure. I dismount it and push the piston in by hand against the bell housing if all else fails. The tear in the m/c boot shouldnt cause a leak if thats all thats damaged.

+3 pushed mine in while it was out and could never get it to bleed. Bought a new one and with a pressure bleeder it was done under 5 minutes.

it helps to have the slave unbolted from the transmish. then you get get all of the air out of the slave much much easier.

okay but how did you guys give the rod resistance? because i know that if there is no resistance the rod will just pop itself out and BAM your gonna have to go buy yourself a new slave

A c-clamp will lock the rod in the retracted position.
