Clutch pedal goes straight to the floor on my 944 Turbo , Help

[ukmastiff]

Oh deary me.

I thought I'd run the car to work today just to check everything is ok before going to have the cambelt change tomorrow. Got in started car and clutch pedal went straight to floor zero resistance whatsover. I have never had any trouble with the clutch which one week ago was as strong as ever.

Is there something that may have snapped / come unclipped etc on a 944 turbo or is this a master or slave cylinder gone as has been suggested to me. I know we have some proper mechanicla gurus out there and as you know I'm not one of them.
I'm also now stuck to get it to the garage who fortunately is only about 20 miles away but its still going to need a tow ( or presumably lift)

Regards Mas

is definately your slave cylinder or master had exactly same thing on mine i change both to make sure all all running perfectly now, did myself with a mechanic mate, needed him to bleed the system for me. access to slave is under the starter motor in middle of car underneath so need to jack up car and axle stands, bit fiddliy but can be done easily enough. cheers

Check the Hydraulics. There's a master cylinder on the bulkhead, a slave under the car & a pipe that connects them. You've got a leak somewhere.

Cheers guys , thats what I was told and from what 944 folk are posting it seems to be almost certain. AA will pick my car up lunchtime and it was already booked in for tomorrows cambelt change so it looks like the bill just went up !

I'll let you know what it costs and I will most likely have both cylinders done.

The good news is that neither part are that expensive, and not (too) hard to fit either. Hence the increase in the bill shouldn't be too painful ...

AA man still not here , apparently hes at Stevenage about 20 miles away).

I have checked reservoir and its devoid of any fluid. Inside the footwell rubber boot has a very small amount of fluid around it , I'm thinking is that not supposed to be there

I have just come home fom work and its half term , my boy has a mate round and they are screeming their heads off , palying Wii etc , do you think the AA man will notice if I put two kids in the car ?

Just changed my slave - cost for OE part from ECP was £80. PLus a bottle of fluid - you don't need more than about 300ml.
Took me about 5 hours I suppose which is a long time in real terms but I'm no mechanical expert so I took my time. 3 weeks on and it seems fine.
If you're not doing it and its going anyway then get them to do both slave and master. I was quoted about 3 hours to do both plus parts, so about 300+vat all in.

ETA Fluid on the pedal is master but the bleed point is on the slave so definitely do both.

Just another one to say for the cost of the parts I did both when mine failed. Also the job is 15-20mins to change the parts and 4-5hours to bleed the system!!! (including a trip to halfords for a long reach 6 and 7mm ring spanner to get to the bleed nipple) hateful hateful task to do on axle stands I'd take it to the garage to avoid the grey hairs next time!

 

[FistsOfHam]

don't forget the 12mm brake pipe spanner.

It is amazing how often this one comes up, it must almost be weekly. But then if most cars are on original parts they are going to be pretty tired by now.

I think I paid £163 inc Vat to have the master changed.

Take the starter motor off first if you are doing it yourself, much easier to get into. The reason they are a pain is the air sits at the top of the flexi as it is at the highest point. Remove the steady from the rear lifting eye and try and get it at the same height as the reservoir or lower. Try bleeding the master cylinder off the car as well before bloting it on as you can get it higher. Not a hard job too do though.

Wow I like the colour of your car! Is that original?

I used a Gunsons Easibleed and it was, well easi!!
Just don't use a tyre with too high a pressure - 33 psi, it turns out, is much to high!!

I thought they were designed to work at 20 psi[&:]

 

[DavidL]

I think I ran mine at about 10 in the end. 20 may be ok, 33 wasn't!

 

[zcacogp]

Ouch - what happened? Much too high and you risk bursting something, and spraying brake/clutch fluid everywhere (which ruins paintwork in seconds ... ) []

[DavidL]

The reservoir was empty so as I connected it I watch it fill and then come over the top!
Too much pressure for the cap. Fortunately I was holding the air line so it came off immediately and I had wrapped an old towel around the reservoir for just such an issue.
Fluid loss was small and fairly well contained.

 

[ChasR]

As said with the Eezibleed, use it at 20PSi, maybe a little higher (not loads) if you have a low flow.

The tip to stopping it leaking is to put PTFE tape around the cap joins, getting a spot on seal.

Anyone used the Eezibleed kit on their brakes? I was going to but I know on some modern VAGs with ABS, it can get a little awry apparently.

Yep, many times and it does exactly what it says on the tin. Just remember that the Brembo callipers on S2's (and Turbo's) have two bleed nipples per calliper. Get a good brake nipple spanner as it can be very easy to round off seized nipples [][][][]

 

[Frenchy]

Nowt worse than seized nipples Paul..........Ohh Er !
I have a Studs Pickavant Double Nipple eezi bleed....not available from Ann Summers oulets i may add !
