Clutch Pedal Not Fully Releasing

[bdknights]

I have a 2002 996 C2 Cab with 48k miles on it.

I just noticed this morning that the clutch pedal failed to fully release when I shifted. It released about 2/3 of the way and then I had to nudge it with my foot to get it to fully release. For the next couple of shifts, it would release about 2/3 of the way and then "pop" all of the way out (it didn't require a nudge but it clearly was NOT a smooth release). It nows seems to be releasing okay but I suspect this is the start of something more serious. I have searched across the forums and read about accumulators and the possibility of replacement of the master/slave cylinders but I couldn't find any particular posting with the same symptoms that I am experiencing.

Any thoughts or insight would be greatly appreciated.

I suspect you have air in the hydraulic lines from the clutch master cylinder to the slave cylinder. I had same problem on my daughters 944S. Eventually replaced the flexible line and both cylinders.

do you have any slip as well? i had a cracke pressure plate which resulted in pedal not coming back smothly or at all but that would only be the case if you clutch started slipping as well and the problem developed instantly and not over time.

I haven't noticed any slip and I put a bit of silicone lubricant on the pedal this morning. I drive it most of the day today and the problem didn't occur again so I am hoping that might have done the trick. Stay tuned....

Thanks for the insight. I saw some similar posts that seemed to consider this as a possible cause. I applied a silicone lubricant to the pedal this morning and drove it all day. The problem hasn't occurred since that time so I am hopeful that this resolves it. I only hope it turns out to be that simple.
