My clutch pedal has started to feel very 'knobbly' when I depress it and not smooth at all. I have a MY99 Turbo. I gather the clutch is hydralic and does not use a cable, should I be worrid about this? it's not slipping at all.

 

try giving it a bleed and lubricating the pedal first might just be something simple

 

Thanks I'll try it. How would I go about bleeding it?

My gearbox oil is overfilled by about .5 Ltr that would not have anything to do with it would it?

 

have a look in the drivetrain section there is a thread on clutch fluid to tell you how to do it.

half a litre gearbox over fill would not cause the problem you have got,in fact i think people actually recomend a slight overfill in subaru gearbox's
