The other day I noticed my clutch peddle was sticking. It works fine, but occasionally it does not fully return to after pressing it.

Any ideas what is going wrong?

thanks,

Search "kinematic lever" or "kinematic clutch pedal lever". Fairly common issue. I think my 97 may need this soon.

I had my pedal box removed and everything was cleaned, the bushings were replaced as well as the return spring and system bleed. Everything works flawlessly now.

Bleed the slave

that happened to me somewhere around 90,000 miles and it was the slave cylinder.

It works as I did it some years ago and now I am due again.

some might argue that its from lack of use and or the slave needs to be replaced rebleed

many others might recommend a kinematic lever change and or cleaning of the pedal box assembly.
Ive ran into this also last summer.

replacement kinematic lever updated version pn: 993.423.519.03 selling in Canada for 102.99cad. might be less in the US I don't know.

It could be the kinematic lever

mine required the clutch master & slave to be replaced

my 95' has being doing it on and off for the last two years.... with good use it goes away. After periods of being parked it sometimes acts up...

my 95 does it on and off as well. Just not enough to really get me motivated to dig into it, but sooner or later i'll have to get to it.

i did this on my 95. new kinematic lever, slave, master and slave hydraulic line. fresh fluid and its smooth as silk now. it is a common issue with 993s.

Mine does this too, I will look into it.

I'd try doing a fluid change/bleed first before digging into the K lever and the clutch master behind the pedals. You'll be surprised how dirty the fluid is in that part of the system. My pedal used to stick, but after I changed out my clutch and fluids it completely went away. I inspected my master cylinder boot behind the pedal but everything looked nice and fresh so I didn't bother tearing into it.

A quick check would be to remove the floor board and lightly lube the pedal cluster at the pivot points. If it goes away after the lubrication, then its probably not the master or slave cylinder and you can focus on the pedal cluster.
