Low clutch resistance Corsa d

[CJMO2018]

Hi guys, hope for some help/advice I had low clutch resistance around 2/3inch from floor before clutch engaged so tried to bleed it Manuel and via easy bleed but nothing comes out the bleed nipple!! And when I use the easy bleeder it’s just pushing it back into the tank reservoir tank and now I have no clutch resistance it’s just spongy and I can’t drive car now I have Checked both cylinders and can’t see any leaks or issues and their is no fluid loss!!! Does anyone know if a reverse bleed from the nipple may work ? CAR IS CORSA D 1.2 clutch and master and slave only covered 5k!! And I have checked them and they are faultless!

There may be a leak that is being retained by the (usually slave) cylinder dust cover/bellows, so you might not see it till this is removed.

Hi, I have had box out and checked slave and all is fine also checked slave at clutch peddle in side car and again nice and dry clutch has only covered 5k I was hoping a reverse bleed to try get any air out may help me in going to try this week

I may be being pedantic here but what you are saying is not clear.

I don't understand how an eazi-bleed can push anything back to the reservoir.

You have got the bottle attached to the reservoir, a tyre attached to the bottle & are trying to bleed from the nipple, yes?

Also, I assume you have checked that the reservoir level is above the clutch "weir" inside the reservoir to make sure that the cylinder has fluid available?

Hi, sorry for any confusion or understanding..... yes I done the easy bleed make sure correct fluid was their and release nipple but nothing comes through I have just been told that I may need to hold the peddle to the floor when using the easy bleeder to open the slave if that makes sense I’m going to try and reverse bleed to later today thanks

This plus the original symptoms makes me wonder whether the clutch master cylinder is worn/dirty and failing to return to the stop when you release the pedal. That last bit of travel is crucial to connect the circuit to the reservoir.

No, that is wrong. The person who told you that doesn't understand how the clutch works.

I advise against that, even assuming you know what it means. (You've referred to the 'clutch slave' at the pedal end which is wrong, and you refer to pushing fluid back into the reservoir, which is not something that Eezibleed would do if you used it correctly and not something you want to happen.

[CJMO2018]

Master and slave have only covered 5k took box off all clean and dry inside also at the peddle end how come you would not recommend a reverse bleed ? It sort of makes sense as it’s easy for air to rise rather than be pushed down

Thanks,
Chris.

Is it me, or does there seem to be about 5 Corsa D problems per week all from recently signed up members?

[CJMO2018]

Haha, I wish I just left it now with the low clutch resistance at least I could still drive it then... I’m going to have a at bleeding it tonight

[E-bmw]

I still do not understand how you can get an eazi-bleed to push anything back into the reservoir, I recommend you either leave it to someone who knows how to bleed a clutch or get the instructions out & try again as somehow you must be missing something crucial.

With the reservoir pressurised there is no way anything can get back up the line to the reservoir.

If you are not getting the results you need with an eazi-bleed try bleeding it using the 2-man method & shut the bleed nipple off with each stroke.

It isn't necessary.. If the problem is one that can be cured by bleeding, then conventional bleeding from the top will resolve it. There are very few situations where reverse bleeding is the answer, and this isn't one of them.
I'm far from confident you know how to do it. The fact you haven't managed to bleed it from the top yet suggests either there's a problem which prevents you from bleeding at all, or that you are bleeding it wrongly. (The mention of fluid being pushed back into the reservoir is especially confusing. The fact you referred to the cylinder near the pedal as the slave makes me worry that we could be completely misunderstanding each other.)
The only safe way to get fluid into the system is by adding new fluid to the reservoir. It's extremely easy to push cr@p back in by reverse bleeding a used system. For all you know the slave cylinder is fine right now, but that could change real fast.

Hi sir, I’m confused also the clutch master slave is at the peddle...and the slave is in to box I’m not novis when it comes to cars but Iv also never worked on Vauxhall cars!!.... when I use the easy bleed set it up release the bleed nipple but nothing comes out!! It seems to me just back pressuring and coming out the reservoir cap! Hence the idea of its either got a shut off at the master or maybe a reverse bleed would work better better I came on here to ask for advice not for you to basically tell me I don’t have a clue! But thanks for your advice

Chris.

You are very welcome.

The slave is at the gearbox end & the master is at the pedal end btw.

It still isn't possible for what you say to happen if you are using the eazi-bleed correctly.

[CJMO2018]

Hi, can I add video on here and I will show you what Problem im haven when doing via easy bleed and via Manuel bleed

Thanks.

[E-bmw]

Just upload it to youtube & then drop a link on here.

[CJMO2018]

Thanks E-Bmw I will try this and send you long later today

Thanks

The clutch master cylinder is the one near the pedal. The clutch slave cylinder is the one near the gearbox. 'Clutch master slave' is not a thing.

Hi Sir, Ok sorry I worded it wrong.

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.

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.
