clutch pedal flat to floor

[yipadee]

After a brilliant day yesteday at the cotswold rally a got withing 2 miles of home then disaster, my clutch pedal stuck to the floor!

I managed to force it into 2nd gear and limp home but wondered if anyone could help with a verdict, am assuming could be a number of things, linkage issues, thrust bearing perhaps!

Iit does stay in gear once in and stalls when you come to a standstill, so assume that means the clutch is still working?

Look forward to your comments

Thanks

Is there fluid in the clutch fluid reservoir? If not, could be the clutch slave cylinder that has gone, leaving you with no hydraulic pressure to operate the clutch mechanism.

I would guess that either the master or slave cylinder seals have failed. Not too pricey...[8|]

will have a look tonight unfortunatley was too late to look last night.

can i fit a new cyclinder myself or is it a garage job?

Thanks

It is a user d i y job I think, if it is at all similar to the 924T which has a similarly positioned starter motor and clutch slave cylinder. I seem to remember wishing I had removed the starter motor on my 924, for better access to the pipe union nut, but I could be confusing that with replacing the loom. Some replacement slave cylinders are pattern made and the pipe entry angle can be different so you might need to tweak the pipe to match the angle. This was certainly the case on my 924T, which I believe uses the same slave cylinder.

I had this happen a couple of weeks ago on my 90 turbo,went to the car in the morning and the clutch pedal was at the bottom of its travel still working only just..,really on the floor,limped in to Leicester OPC (it is next door to my work)they had a look,changed the fluid,and ordered a buffer or damper (the part was 2 pounds) must be small,and so far it has been fine the pedal is really high and the pedal is light and springy,maybe start with a fluid change?

i have also noticed a gravelly feeling when the car stops under breaking,feels like stone in between disc and pad but isn't any suggestions?

cheers

If there are no foreign bodies between any of the pads and the disc, then it has to be the pad however inconvenient this might be. It is possible for the inner edge of the pad backing plate to rub against the radiused section of the inner part of the disc bell (outboard) if the pads are a bit down on their thickness combined with worn discs with say a one millimetre lip.

This was the first thing I attempted on my car. Apart from access to the underneath, and the starter dropping on my forehead, [], it's easy to change the slave. Master is at the top, and even easier.

I had exactly your symptoms but obviously low fluid, with no sign of leaking from the master so knew it was the slave. Slave was about £40 plus some fluid. I used clark's garage instructions.

If you managed to change the rad then this will be a a piece of cake!

had a quick look in car and fluid has droppped in reservoir,haven't jacked car up yet, which side is the clutch slave cylinder and can you only access from underneath?

also how long u reckon it takes to replace the cylinder and bleed if reqd, if you were a mechanic in a garage?

Nearside I think, right behind starter motor. Only from underneath.

Took me about an hour, and I am a REAL non-mechanic. I'd not done more than brake pads on a MK II Escort before!

Check around the master for leaking first, is there any fluid on the carpet around the pedal? If not then the slave is the probable culprit.

thanks paul will give it a go this friday

Hi yes it is on the near side, drop the starter but leave the cable on, cylinder is just above, blead clutch before refiting starter. Regards Berny.

I know this is probably sorted now(really old thread i know) but i found the mysterious part numbers(i found my cash sales invoice) for the bits that fixed my clutch with the same symptoms....they are


P999.924.001.40 Bush £0.76
P999.703.183.40 Buffer £2.08
These parts with new fluid fixed my clutch and it was on the floor nearly undrivable,fitted by the local OPC,this was a month or so ago still perfect,nice and high,springy too!

I was impressed anyway,

i fitted slave and found ot was the master so have replaved that also, although i think may have cracked the plastic pipe from top of cylinder to pipe which connects to the reservoir, short of replacing again at £60 a go any suggestions, silicone sealant perhaps or just keep topping up?
