Clutch pedal to the floor. Oh dear!

I'm pretty certain that my cars are jealous of each other! Within a couple of months of getting the 944, the Rover broke down with a mysterious fault. I've finally got it back after it had spent a month in the garage, but I've just climbed into the Porsche and the clutch pedal dropped to the floor and stayed there just before I was going to start it up. The clutch fluid resevoir was totally empty (except for some nasty looking residue[&:]) I've always been warned that having a wife and a mistress was a bad idea, now I know why![:D]

Anyways, it sounds to me like a classic example of the seals failing in the master cylinder. I'm going to have a quick scoot around the forum to see if anyone has had a similar issue lately.

Does anyone have any ideas of another possible cause for these symptoms?
 
Could equally be seals in the slave cylinder, or either the hose or steel pipe. Look for evidence of fluid in the car or under the car (in the car = master cylinder, under the car = everything else!).
 
Put some clutch fluid in and try and pump up the peddle I would guess slave cylinder! you can look under the car for fluid! if its master cylinder look for a leek inside near the peddles. If it's slave there not to bad to do or fit a repair kit. Berny.
 
Thanks Tref. The master cylinder is certianly wet and there is some fluid on the carpet, but not as much as I would have expected. Maybe it's all soaked in [&:]. I couldn't see anything on the floor, but it's a gravel drive so it wouldn't show up very easily anyway.

From what I've read from my search it sounds like I can get a seal kit for it and that it's probably worth replacing the flexi hose and doing the slave at the same time. I'll ring OPC leicester tomorrow...

Edit: Thank you Bernard too. I was a bit too slow replying to Tref so I misssed your post
 
if its leaking fluid its most likely slave cyl if you pull out bung in bell housing fluid will most likely run out from that area Porsche don't do seal kits anyway false economy as usually the cylinder is shot, if you have difficulty in finding the part give me a call

If there's fluid here it's the master, if the slave is leaking you don't tend to see fluid as it's all thrown out by moving parts. That said, you're sensible to change everything unless you know the slave is recent, the seals are likely to be as close to failing if they are the same age and the hose is cheap to change.
 
Bert, Porsche do do a slave cylinder repair kit. 928 116 901 00. Be prepared to sit down when you ask the price of the flexi!

Thanks guys. It's good to know theres so much advice and support on here!

I've seen flexi hoses for about £30. Is it posible to have one made up for less?

It seems the rebuild kits for the master cylinder aren't quite as common as for the slave. Does anyone know where I might find one?

From the link in the alternative parts thread it suggests that the rebuild kits for the mercs W123/124 are suitable. Does that mean that the cylinders are interchangable too? (probably a really dumb question[:D])

Also, is it silly for me to be contemplating changing the reservoir pot and lid too? [8D] Maybe the bracket would benefit from a sandblast and repaint ...

I had a new flexi pipe from ECP a few weeks ago for about £39. None of the local hose people could make one for me, not even Pirtek.
New slave, also from ECP was £77, and the seal kit from OPC Swindon £15 last year.
This time the flexi had worn a hole by rubbing against the corner of the cam cover.
 
Get a new master cylinder Simon. They are cheap enough relatively speaking. They are a doddle to fit but I will give you a hand to fit and bleed it if you like.

He just wants the cottage pie Simon, dont trust him! [:D]
 
Mercedes W124 from same period uses excately the same FAG cylinder,Only a dust boot is a bit different...... I suppose you can buy a repair kit from you local parts store quite cheap.
 
My pedal sinks on a regular basis, holds itself fine if I pull it back up again though before I start the engine. Pedal is fine and gives no slip in normal operation once warmed up, both cylinders have been changed, as has the clutch to no avail and the car leaks no fluid. I've never understood what's happening and figure that I'd end up in more trouble if I investigated it than I would if I just left it!! [:D]

I think you're right!

Cheers for all the advice guys. I'm out of the country at the moment, but I'll have to do some shopping around when I get back.
