clutch problem

Andy_Wright

hi, im having trouble i have no pressure on clutch pedal, was wondering how i go about bleeding it, any help

there's a bleed nipple on top of the clutch slave cylinder on gear box. fluid is from brake fluid on brake master cylinder.
check for fluid leaks around pipe work and under clutch/flywheel housing.

Andy_Wright

already checked for leaks cant see any at all, but my brake fluid was very low, so toped up n was wondering how i go about it, i found the bleed nipple just under battery ontop of gearbox, so is there any special way or just like bleeding brakes, only i dont want do more damage than good lol

I pump the peddle a couple of times hold it down open the nipple
Nip it up let peddle come up
Hold it down undo the nipple let the peddle go to the floor
Nip up let peddle back up and repeat until you get a good clutch
But if the fluid was low I would say your clutch cylinder has gone or it's the master cylinder
I would check to see if the pipe is on the slave cylinder as the rubber o ring inside can fail

i had to use a vacuum bleeder after fitting a new csc
used a gunsons pressure bleeder with the pedal down to feed fluid to the slave thru the bleed nipple
then used the gunsons cap with a vacuum bleeder to pull the csc closed then pressure bleed it again
final step pump the pedal 30 times 🙂

I fear your slave cyclinder has died my fluid kept going down then eventually couldn't get it out of gear if left overnight had to pump peddle a few times before it would come out, finally it died and no clutch control at all. I had to replace the slave cyclinder. I've personally never had any problems bleeding the clutch and I've had the engine in and out a good handful of times now

As above sorry

mine was a complete shit but it may have been down to the twin plate clutch and the extra force of the 2 layers of springs lol

well ive tryed using a pressure kit and nothing, not even air comes out the nipple

Make sure the union is on right as this will stop fluid passing through if you got fluid the it could be your master cylinder

Andy_Wright

my fluid dosnt move, didnt go down, changed vbrakes and bled them, didnt notice fluid low, but clutch peddle was starting feel spongy, so read up and said they work on same res, so went to bled and nothing, no air or fluid, but lost all clutch, so tried air pressure system and still no joy, cant even get air come out the nipple 🙁

never had any trouble bleeding clutch slaves on any Vauxhall. as faltbeat said, bled them this way and now with a vacuum bleeder. could be your master cylinder has failed?

Andy_Wright

ok i got it so the nipple is working but it like there a vacum and it sucking air in before out

flatbeat

It might do for a few pumps mine did then went ok
If your slave cylinder has gone you won't be able to get a good clutch or it could be the o ring inside the union

Andy_Wright

cheers for the info, and all the help, going have another go tomoz c how it goes 😉

Worst case use a syring to back feed fluid back into the resovoir

Andy_Wright

ok im still no better, so im either being dumb or sumit broke, so i give u quick run down for your ideas, so first off the brake pedal moved down when foot kept on pedal at lights or traffic, brake creap, so thought air, bled brakes but still noticed it but not as much, then clutch peddle started bein funny, felt like first inch did nothing, then when fully down it was hard get in gear, when it warmed up ut was fine, so went to bleed n now no pressure, everything seems be pointing to faulty master cylinder, does this sound rite, or do you think something else, the is no leaks and not losing fluid either, oh also just so i know im doin it right, does engine need be running or not, do i pump peddle or just press it down, im just trying cover all angles so i can get it down over weekend, any ideas welcome

flatbeat

Sounds like it's your clutch slave cylinder

Andy_Wright

oh right, would clutch slave cylinder cause break creap tho

flatbeat

Yes because your break reservoir feeds the clutch master cylinder
