clutch pedal sinking??? HELP!

[ickleredders]

right had so many problems with my cupra it must be a record!!

i had a terrible vibrating clutch and anyhow turned out it seemed to be the wrong one for the car!! so my mechanic got a clutch off another cupra got it refurbed and fitted and all it great now!

but.....the clutch pedal seems to sink if i leave the car overnight and go to start it in the morning it has sunk a bit ( enough to make it extremley difficult to put the car into gear) if i bring the pedal back up with my foot and pump it a few times it seems ok, what could the problem be?? tried bleeding it but didnt seem to need it, could this have anything to do with the dreaded problem everyone seems to be having with their clutch pedal snapping??

any help would be much appreciated

thanks

Well the brakes and clutch share the same servo which have vacuum assistance
Are you trying to put it in gear when the engine is off ? As there will be no vacuum being generated

no when its on i turn engine on put it in gear to go and if i dont pull the pedal up you cant get it in gear :s

Could be the clutch slave cylinder.

Check for a leak where the hard pipe enters the slave cylinder - I've seen this slow leak allow air in, which causes what you have.

Replacement of slave cylinder is very easy, and not too pricey from EuroCarParts etc.

i had this exact same problem on my cupra when i first got it. Turned out to be a loose nipple on the slave cylinder. Got it tightened and all was fine
