Low clutch resistance Corsa d

The Eezibleed systems I've seen work by applying low pressure to the reservoir and having somebody open a bleed nipple on the slave cylinder. Sometimes the bleed nipple is on a hose (remote from the slave) and not directly screwed into the slave, but it's still plumbed into the slave.
Are you thinking of some different layout?
I haven't tried using Eezibleed to pressurise a system with a lot of air in it and then not bleeding it out to release the pressure, and that's the only way I can think of that would lead to fluid coming back into the reservoir.
You can also use such systems to reverse bleed via the nipple, although yes the most common way is from the reservoir outwards.Are you thinking of some different layout?

Although with the wide range of products out there...who knows what exactly he has or what he actually tried to do, or whether he did it correctly.
FFS, if you just undo the nipple they'll almost gravity bleed themselves with a little patience, and then just a final bleed with a few pumps etc.
Of course he hasnt stated why he had the gearbox out, why any parts were originally changed, whether a competent person did the work, whether proper quality parts were used etc etc. So no doubt any problems now are self inflicted and things may not even be back together correctly so they can work

But surely all that would do is to put as bit more pressure on the air in the line until you open the bleed nipple, not push fluid back to the reservoir.stevieturbo said:

It still isn't possible for what you say to happen if you are using the eazi-bleed correctly.
Assuming it is the same as many cars with a concentric slave...yes it is.Because the bleed point is not at the "end" of the circuit, hence products like an eazi-bleed are in no way whatsoever the correct way to bleed them
Take the car to a competent mechanic before you cause further damage and cost yourself even more money. Bleeding these is an extremely simple process, much easier with 2 people and no attempt at using anything fancy.
That would require there to be more pressure in the slave end of the system.......... Where would that be coming from?
The only possibility would be trapped pressure if the master wasn't returning properly, but the giveaway there is that it is trapped, so that doesn't help explain it & even if it did, as soon as you open the bleed nipple it isn't trapped, so still no fluid returns.
There is no doubt at all that the old-school 2 man bleeding method is the better way, hence why I mentioned that or to take it to somewhere competent.

It's not a problem I've ever seen, and I don't know whether it's happening here, but my thought was that if the slave bleed nipple was blocked or not being opened properly and there was air in the slave, then applying pressure at the reservoir would push fluid down the line and compress the trapped air; when the pressure was removed from the reservoir the air in the slave would expand to its natural volume, pushing that extra fluid back into the reservoir.GreenV8S said:

OK, I get that if that were the case it would be possible, but that doesn't sound like what the OP is on about and it is only letting back out what you put in which you wouldn't see as the eazi-bleed would be in the way. The (little) pedal he did have wouldn't have gone.The OP talked about having a pedal, then losing it after bleeding & only getting fluid back.
For him to have a (crap) pedal and then not then the master would surely have to block that in too & I can't see it being possible.
I reckon he has not enough fluid in the master reservoir and has emptied what was there through the bleed nipple, with the car not level. Then when he dropped the car back down level some fluid has gone over the "weir" & he thinks it has come back to the reservoir.

Whether the bleed point is at the end or not with an eazi-bleed connected to the reservoir, enough fluid in the reservoir and pressure applied to the system correctly there is no way fluid can come back up to the reservoir.

And as said...there are different ways to connect devices like an eazibleed. Or if it is connected to the reservoir, if it is not totally sealed it will entirely fill up the reservoir and leak out. Or even if it is sealed, by design it will fill up the reservoir anyway.That would require there to be more pressure in the slave end of the system.......... Where would that be coming from?

So his perception of backing up....is probably totally wrong in the first place.
And an eazibleed would not generate enough pressure IMO to bleed a clutch where the bleed point is not at the end, natural bleed point in the system.
Bottom line....if you dont know what you're doing, take it to someone who does before you cause more damage and I've come across plenty of so called mechanics who've f
ked up setups like this, and end up ( probably needlessly ) replacing master cylinders and all sorts. All at the customers expense of course.Hi Sir, I think I have found cause it seems the the plastic connector where the bleed nipple is located on to of the box seems to be drawing in air when you move it the slightest bit so I’m guessing the seal inside has gone brittle as their is a lot of movement in going to replace this and see what happens
Thanks

Hi, It was to dark to start playing with it as I didn’t finish work till late on but I’m going to try and take it off tomorrow and check if the seal has hardened/gone brittle I’m sure it’s in the shape of a top Hat lol... the slave and clutch where replaced 5k ago but who ever changed this cant of checked the condition of the bleed nipple housing seal hence why I had low clutch pedel resistance in the first place maybe.... I’m just dreading how much Vauxhall with change for a new 1
Thanks
Thanks
This reminds me of a friend who had a clutch fitted to his Astra .
The fking clueless mechanic doing the work replaced 5 slave cylinders because of leaks, blaming them all being faulty for leaking at the hose joint.
This despite him being told that he likely fked up the o-ring inside the fitting...and there was even a tech note with the slaves to inspect this.
5 fking times !!! That's gearbox out every time. And yes eventually my friend had to show him what he was fking up before it was finally fixed.
The incompetence out there is unreal.
