Doblo 1.9 jtd 2004.
I just turned the car over forgetting I was in first gear and now the clutch pedal goes to the floor with no resistance and does not feel "attached" to the car!
I think I have a hydraulic system but it feels like a conventional cable snapped. What am I looking for here!!
I ordered a "CD manual" yesterday but have only had the car a week.

hi,
the hydraulic slave cylinder is on top of gearbox ( below Battery tray)

IF something has failed then there would normally be spilt oil / fluid around there,

there is normally a small while pot around the engine bay that serves and the clutch fluid reservoir.. it'll be empty in all probability..!!,

I found the offending item. A plastic actuator that transmits force from the slave cylinder to the clutch actuator arm. End snapped off!! Found both bits and nipped into work (on my day off) to make a replacement out of stainless steel. (lost the end of the original plastic one for the picture )





Now it's fitted I have to bleed the system. Yes I did lose fluid. I didn't even realise I had a hydraulic clutch at the time. The instant failure felt like a cable snapped.

There is a bleed nipple on top of the slave cylinder but no hex to loosen it as you would on a brake caliper ? how do I crack it open to bleed the system ?

sorry - all my dealings have involved conventional nipples.

best post in TECH section - put "Clutch bleeding" as 1st line of title ; - )

if all else fails- call a FIAT dealer

Ok.
I've had a good look through this forum and many people are having difficulty getting the information required to bleed the clutch hydraulics.
I will go and see what I can come up with, take some pictures and post a new thread with a link here...:bang:

I would carefully use grips to try and wind it out..,

I'm wondering if it's like an oiling point..,
where the factory pressure fill from the bottom..??

Charlie

Possibly pressure filled from there. :chin:
I had a go at pressure filling with my kit that attaches to the resevoir. (never used it before) Didn't go well.

So far I have tried to fill this system from the top with pressure and bleed from the bottom with gravity but neither worked.

The correct way to open the bleed nipple on the slave cylinder (for those reading this for help), is to partially retract the inlet pipe after removing it's retaining clip. It is sealed with 2 o-rings so once the first is past the bleed nipple, fluid flows out of it. I only got fluid though, no air bubbles.

I have put everything back together still with no clutch action but now I have a better idea of what I'm up against I'll buy some more dot3 (as mine is all over the driveway, don't ask !) and try a pressure fill from the slave cylinder.

Had that, another bit of plastic C**p:bang:
If it happens to you Remove broken part from pedal then remove clip in cylinder while holding piston in, Fiddly but not to difficult let broken end fall out & REFIT-CLIP Make new rod assembly & re fit make sure you keep piston pressed in cylinder at all times.Mine broke repaired in 45 min with drill & grinder + bit of gash bar
Why do manufacturers make this junk

I have managed to successfully bleed my clutch hydraulic system now.
It was surprisingly easy, once I had made up the little bottle and pipe arrangement I used.
I will post a picture and description this weekend

this happened to my mates doblo,,,don't panic,,nothing major,,defo that white plastic junk piece down at the pedal,,newer models I think have steel ones,,,,he took one out of a punto and it fitted so theres always plenty second hand ones

This piece that broke was sticking out of the slave cylinder under the bonnet. It's not part of the pedal assembly. Still a bit of grey plastic junk though
