I have an '02 C5 2.2 HDi Estate, and just today the clutch pedal went absolutely solid, and won't push down.
I've seen some reference to a "pull" type clutch lever, but I don't quite understand this workings, and what to look for to fix.
I have the air-box out, but there doesn't seem a lot of room behind the slave-cylinder. I havn't taken it out yet, in case I can do some more analysis of the problem.
Any suggestions ?

Re: Clutch pedal solid !
maybe the flexi hose to the slave cylinder has collapsed internally causing a blockage???

OK....hose looks good cond., but I will check it.citronut wrote:maybe the flexi hose to the slave cylinder has collapsed internally causing a blockage???
I have, however, read something about a clip or pin that holds the thrust bearing in place can fail, but can't yet figure out if
this fault can be seen behind the slave cyl., and if it is then a gearbox out fix..............

Re: Clutch pedal solid !
It does appear to be a pull type clutch (the clutch is reverse acting compared to a 'normal' clutch, ie the release bearing is pulled away from the engine to disengage the drive). Normally if the bearing breaks free of the clutch then the pedal goes to the floor. Wonder if it might be a mechanical problem at the pedal end rather than something else? Odd one...

Re: Clutch pedal solid !
Its unlikely to be any of the hoses in the clutch hydraulics, as they are made of high pressure thickwall nylon.
I have heard of the release bearing seizing on the shaft in the clutch assembly, but suspect it to be a rare occurrence.
As your car is a 2.2, does it still have the dynamic clutch assembly fitted? That might be where the problem is as they can disintegrate with dire consequences. Any nasty noises from the clutch operation before it went wrong?
Could also be the clutch release arm pivot bearings. They can collapse and seize on the pivot shaft. Seen that on a few PSA cars.

Re: Clutch pedal solid !
If the C5 clutch is like the Xantia HDI, it will have a conventional hydraulic pedal cylinder complete with a (sealed) reservoir.
So a possible explanation is that the snap ring on the pull clutch has let go, the pedal has gone right down, been manually pulled back up, and without the normal positive pressure due to the clutch springs, the pedal cylinder has sucked in fluid from the reservoir. As the arm at the clutch end will already be at the limit of travel, the pedal will now be solid.
