Clutch not disengageing

Hi all,

Just bought a 2010 Peugeot expert teepee 2.0hdi 120bhp in very good condition but with a slipping clutch.
I found the clutch pedal hard to press and the clutch was slipping so i bought a luk clutch & DMF which was the exact part numbers as the one i removed.
I changed the clutch kit and slave cylinder on my back in the driveway and tried to drive away but the clutch would not disengage and i assumed that i put the clutch disc in the wrong way around. was not willing to remove the clutch again so gave it to a mechanic friend to correct my mistake.
Issue was when he rotated the clutch disc the way he assumed it went the clutch still would not disengage so he changed the master cylinder as this was the only old part left.

So now i am at the point that i can confirm all the components are correct and changed but the clutch pedal is not disengaging the clutch!
what the mechanic has just found is a socket wedged in under the clutch pedal which he has removed but as the box is not fully in again for him to test if this was the issue why my clutch would not disengage.

My questions are is if the socket been removed from under the clutch pedal has not fixed my issue what is the next thing it could be?
If the socket was pushed in there for a reason what problem was the previous owner trying to correct?
will an issue with the foot pedal stop full force being applied to the slave cylinder to push the release bearing to disengage the clutch?

I'll guess the mystery wedged socket is either a red herring or possibly aimed at something else: I've read on certain gearboxes it is possible to overextend the clutch springs (taking them over centre, and then don't return) - the fix for that issue is to prevent pedal going all the way to the floor (I e. Shove a wedge under it)

Shame to have clutch plate backwards - I must have been lucky as the ones I have interacted with have had very clear markings "engine this side" or similar so have been saved from that issue.

It is possible the new slave cylinder is faulty, but equally I would have another go at bleeding this system - can be a real pain to bleed at times. So you could be squishing an air bubble so loosing some disengagement action??

I used pressure bleeder (gunson easybleed - cheap and commonly available. Plenty of alternatives) but vacuum bleeder might also work well for this task.

Thanks for the reply Matt. I did have issues bleeding it but then used an easy bleed which worked much better but possibly some air still there. I am going to concentrate on bleeding it again and work out why the socket was where it was as I still think this has something to do with it. The slave and master have been changed so hopefully I can mark them off as the cause. Bloody annoying as a I have never had issues before changing a clutch on anything. Was yours a SAC or the normal type

Normal clutch for me (at least I think so - was a failed slave cylinder on mine so didn't delve into the clutch itself - replaced around 40,000 miles previously according to the service history so left it alone)
