Someone replaced my clutch pedal with a wet sponge

[944boy]

So I have 105,000 miles on my 05 2.7L 6-speed Boxster with the original clutch. Recently the clutch started slipping under "normal" circumstances. Before I really had to do something stupid to get the clutch to slip. Now a brisk WOT shift into 6th would slip unless I let off briefly. I was planning on ordering the clutch kit and replacing it over thanksgiving.

That was until yesterday...

I was on my way to head up to a date in San Francisco and all of a sudden the clutch goes spongy. It feels like it never fully disengages and has zero feel. Feels like I'm stepping on a wet sponge. It slips easier it seems and is hard to take off from a start, especially on a hill... remember the SF part?

So it didn't explode on my and today I bled the slave cylinder hoping that would be the solution so I could at least drive it.... nope!

Now I am trying to figure out the possibilities of what has gone south so that I can order parts in one shot. And I don't want to replace the clutch to find out the problem is still there and the master cylinder is dead. Now if I had more positive cash flow I would just replace everything for good measure. Sadly cash is not freely flowing right now so I need to keep it to parts that are actually worn out.

I did have an issue with my 944 where the release lever pivot backed out and it felt similar.

Has anyone else had this issue? I also thought about a light weight flywheel but that is a whole nother can of worms.

Sounds like a loss of hydraulic pressure, slave cylinder may be bad, check for traces of fluid on floor.

When I bled the slave all the dust that I could see was dry. I did get a bit of air out though. Being the cheapest part I will replace it and try again. No drips on the floor. This car has yet to leave a drop of any fluid on the ground the entire time I've owned it.

If you're clutch pedal felt nearly perfect before, there was no air in the system.

Air leaking in is the cause of... well... A leak. lol

Its very possible it only leaks under pressure and very very slowly. Having room for pressure to escape will cause your pedal to feel like nothing.

The slave and master cylinders list at ~$250 together for OEM parts. For that kind of money, it may be worth the hassle to replace both of them. If you need to do a clutch anyways, do all 3 and your pedal should feel like a million bucks

You drove on a bad clutch way too long, so why suspect the hydraulic system? It may be your clutch disc coming apart and jamming thing up. You'll probably need a new flywheel. I hope you're not still driving it.

Check your clutch….original at 105,000 - you have been on borrowed time for a while. Surprised it lasted this long. However, it IS most likely DOING DAMAGE each time it is being used. Time to get out that secondary car (we ALL HATE that part). Get this puppy to the doctor STAT!

NOTE: if you buy a slave you will also have to buy a new line and connector as they are not a direct replacement any more.

Originally I had ordered the slave and master cylinder but failed to notice that you have to order two additional parts. The little connector and new line added $320.00 to the build bringing the upgrade of just the slave to over $400.00. Porsche is mighty proud of these parts.
