clutch pedal stuck all the way down...

[ehD]

Do you have a leak?
At the time I'm not sure, it was pouring heavy rain. The day after I had it towed there was no sign of leaks.

Is the underside of your car wet or sprayed with hydraulic fluid?
Honestly I don't know what hydraulic fluid is but yes, it was very wet from the rain.

Can you put the car in gear?
Yes I can shift between all the gears.

With the engine On? Off?
Yes and yes.

What's the fluid level in the Hydraulic Fluid Reservoir in the front trunk?
Hrmm I'm not sure I don't have the car with me right now...

At or Below the FULL line? If below, by how much?
Ditto...

Personally, I don't think you have a burst Hydraulic line. From your description so far, I'd say that something mechanical broke in the clutch itself, or you have a failed Master Cylinder. But, I'm not certain of anything since your description is so lacking. Give us more information please...
The clutch seems fine.. it seems like its the pedal? I could be completely wrong... Are these repairs going to cost an arm and a leg? I just got this car 3 days ago and I have a feeling I'll be in a world of pain in terms of repair costs soon =(

Hi,

OK - better description, thank you. I think I'd be inclined to bet on the Master Cylinder. Relax, the pain isn't so great, especially if you can do the work yourself - are you a DIYer? You can save a bundle if you are.

The Master Cylinder is made by Lucas I believe (the Brake MC is) and so a generic part may be available. The Porsche PN# is 996.423.171.05 and it runs $50 or so. But, first, you need to confirm this by checking the hydraulic fluid level (the Brake MC and Clutch MC share the same fluid reservoir).

If it turns out not be be the MC, then I'd suspect the actuating arm which transmits the force of the Slave cylinder to the Pressure Plate by acting on the Release Bearing. In Porsche Speek, this is called the Clutch Operating Lever - PN# 012.141.71.B. This part lives in the Bellhousing and if replacing it, I'd consider just doing a new clutch at the same time to ammortize the Labor costs. But, I doubt this is the culprit, because the Clutch Pedal would operate normally, but with no effect.

I'm still betting on the MC. Is there a possibility that the Dealer or Seller would lend some assistance with it since you've had the car such a few days? Do you have recourse against them under Lemon Law or other Consumer protections? I'd look into this before too much time goes by...

Happy Motoring!... Jim'99

Well I got it towed to a shop. The guy who sold me the car actually picked me up after the car was towed and we really haven't discussed who's responsible for anything in particular. I bought it directly from him through craigslist and just waiting for an estimate. He mentioned he had some credit at this shop, so we'll see how everything goes. I would someday like to be a DIYer but really don't know much about cars.

If it is indeed the master cylinder though, what could cause this to break in the first place? I'm not really sure if the blame is really on my side or his side or 50/50.

The thing is I've paid off his loan to the bank for the car and am still waiting for the pink slip which is being sent to me. We've already completed a bill of sale so that I can transfer ownership without his signature.

I really appreciate all this insight and will let you know the results. I'm really excited about being a boxster owner but I feel like I really need to brush up on all of its parts and how to troubleshoot things. Is there a good place to start to understand how the car works? To be honest this is my first MT car and I had just learned a week ago and I can drive it well enough but don't really understand all the mechanics behind it.

Thanks so much for all the boxster wisdom!

Be prepared...
I had the same thing happen to mine... turned out it was the line from the Master cylinder to the Slave cylinder. Parts and labor with bleeding the system and new fluid was almost 800.00 at my local dealer.

Dont let them talk you into replacing the brass fittings at the ends of the line if this is indeed what it is. You dont need them and they are over 100.00 each.

Best of luck!

The master cylinder failing is a pretty unpredictable problem if that's what it is. What usually happens is one of the internal 'O' rings starts leaking so fluid pushes past the rings and drops the pressure until there is not enough pressure to push the pedal back against the helper spring. Since it's internal, there's no easy way to tell it's going to happen.

If it is the master cylinder, I'd ask him to take care of it and if he offered to split it that would be acceptable.

Good luck!

Okay the shop says its the slave cylinder and that it was leaking. And that the pressure plate probably needs to be changed and that I might as well get a new clutch too. Jim you seem to be right on the dot...

Is it normal for a shop to order the slave cylinder before contacting you? I stopped by the shop and was told that they had already ordered the slave cylinder before I even knew I needed one and that it would be needed to test for further problems, like the potential pressure plate issue. They did tell me they'd call me once they had the part.

$180 for the cylinder, $200 for the labor for the slave cylinder alone. Does this sound reasonable? I had another car shop check the cost of the slave cylinder and it was only $90. I'm just kind of shocked after hearing Jim's $60 master cylinder cost and just imagined a 'master' cylinder costing more than a 'slave' cylinder.

update:

so i got a new slave cylinder and the car worked fine for another 2 days and again the clutch pedal stuck to the floor.

now i'm not sure what to do, and not sure what the standard of service is. will i have to pay for the towing again (last time it was $175 for 25 miles!) or should the shop take care of it? supposedly the repair is under warranty for 6 months i think but if its the same problem and a different part what does that mean. does it mean their recommendation of a new slave cylinder is wrong?

i don't know how to go about this and unsure whether i should be responsible for them putting in a wrong part. also they said it could be the transmission if the slave cylinder didn't fix the problem. i'm really confused, and this shop seems to have been recommended by several people.
