How much clutch pedal travel

[bilko0795]

Hi guys having just bought my first S2 at the ripe old age of 51 i seem to be asking a lot of questions from the forum here is another one when i depress the clutch pedal select a gear release the pedal it comes up and the last 3" it clunks its as iff the spring is to powerful so you can imagine when you drive the car everytime you change gear you get clunk has anyone else had this problem???

My clutch pedal has a life of it's own, usually caused by worn linkage. Long as your clutch is working ok, I just learned to live with it at the moment. Let me know what you find out might help me too

Two things to check. First off the pedal has an overcenter spring which can sometimes break and fall out.



2nd is the linkage to the master cylinder, there is a flexible rubber section that can fall apart and cause trouble. Basically keep an eye on it as you push the clutch pedal in, if it bends out of shape its done for.

Mine snapped once on the at Bristol when I had to get back to London. It is a common issue with these cars. Mine did what yours did and then as said eventually snapped!

Got a friend of mine to fabricate a new part. Think it was the rod if I remember what he said correctly?

Hi guys had a look at the clutch pedal today and from the diagram that macandmar sent me it is no 6 and it does bend out of shape whats the solution can you buy the broken part iff so anyone know the part no.

cheers.

No.6 is the return spring. If something is bent it is highly likely to be the master cylinder push rod and universal joint. A notoriously weak link in the clutch pedal arrangment and something that EVERY owner has had fail on them at one point or another.

"Rusyy" on here sells a repair clamp, or failing that a new Master cylinder is required....

HTH

I have a design for a repair clamp that I'm getting made soon, I hope - I've been testing the prototype for a few months and it works well. Next projet is the pivots, as I think mine are contributing to a really sticky pedal action.

[bilko0795]

had another look today and its def the master cyl pushrod and not no 6 is there a thread on here on how to get the master cyl off im having trouble getting to right hand bolt under the pedal thats attached to cyl.

It's fairly involved on a RHD car, as you have to take off all the turbo heatshield, airbox etc. etc. The bits inside the car aren't too difficult, just takes a while to get the right tool in there

the CQ20v / 3B master cylinder is an upgrade on the ABY one as it doesn't break, AFAIK its a straight fit and half the price

Really? Why did we get a chocolate one for the superior ABY then?

[Error404]

ask the accountants

[mcandmar]

I think the engineers were on a rubber fetish when they did the ABY with squidgy flywheels, rubber linkages and what not.

Dont really remember having much trouble changing them Bilko, almost sure it was a job for the 1/4" Teng ratchet set. Best tool i ever bought, use it for everything as its so small and easy to get into places.

[Greg_S]

Thats worth knowing, im about to replace mine while the engine is out. What is the difference between them? Have you got the P/N for the 3B version?

[mcandmar]

8A0 721 401 ABY/ADU
893 721 401 D For everything else

Question is are the piston sizes the same, i suspect the ABY is larger so earlier master cylinder might give you a firmer pedal action.
