According to my Haynes, the 'early Fabias' (ie Mk1?) had a stop behind the clutch pedal, just below the master cylinder, to restrict down travel. This is missing on my 2002 1.4 16v, but I'm sure it should be there. Can anyone confirm this?

 

The pedal travel is excessive, and occasionally the service garage tries to convince me that the clutch needs changing because the pedal comes up so far before it bites; but this is because they're judging it in distance from the floor.

 

I don't suppose anyone has a part number, or a source?

I've never seen such a thing, I had a very early 2000 1.4 16V and that certainly didn't  have a stop beneath the clutch pedal.

My 2.0 doesnt have one either.

A stop would get broken or make a noise, I've never seen one on any car I've driven.

Many cars have one under the throttle pedal but not the clutch.

Er, master cylinder -> hydraulic clutch. Being able to consistently run a fairly high biting point without risking clutch slip is one advantage of a hydraulic clutch.

Perhaps it's up under the dash out of sight.

Ok, so it's invisible.

The stop is to prevent the driver breaking the master cylinder pushrod, later vehicles use a plastic one.

 

The button is to reduce noise & will make less difference to the down pedal dimension than a floormat.

 

It will have no effect on the height of the biting point.

Thanks for the responses.

 

I've uploaded the illustration from the Haynes. However, it looks as if mine is later than that; it's got the button stop on a metal bracket in that position. Actually though, the pedal hits the trim panel around the steering columnn before it gets to the stop.

 

As people have pointed out, the actual bite point on a hydraulic system is fixed by the hydraulics (in spite of what the local dealer has told me, twice!). My problem is that it's an awfully long way from the bite point to the floor. If I set the driving position to enable me to get the pedal right down, my right leg is too bent on the accelerator. In practice, I rarely put the clutch to the floor, but it doesn't seem ideal, which is why I was wondering about that early clutch stop. Hey ho, back to the drawing board.

Why on earth are you trying to push the pedal to the floor?

 

You risk overthrowing the pressure plate and its really uncomfortable to control the clutch with the leg bent at a larger angle then necessary.

 

If you are very tall, perhaps too tall for the vehicle I could understand or also if you have a problem with the brakes where you need the full pedal travel to the floor to stop.

 

I will happily swop your problem for mine where frequently the clutch pedal has to go to the floor to declutch and the bite point is very low, been trying to resolve it for months, my final theory is the internal spring in the concentric slave cylinder has broken, I have a new one after replacing everything else more than once but I'm not dropping the transmission to find out, I have found a wat to live with it.

Actually the bite point depends on clutch wear and pressure plate diaphragm strength rather than the hydraulic system.

That would require my car to have done 60_000 miles with no clutch wear.

 

It also argues that the claimed advantage of a hydraulic clutch being self-adjusting does not exist.

It is self adjusting inasmuch as that the system takes up slack by taking additional fluid from the reservoir but it cannot compensate for weakened diaphragm springs.

Where do I say that it does? All I say is that the hydraulic actuation has, for a driver who's wallet is attached to the clutch mechanism, the advantage of acting as an automatic slack adjuster. 

Well, this is all very interesting, but it doesn't really get me any further. Why does the clutch pedal have to go down such a long way below the bite point before it reaches the floor? For the sake of clarity: I don't push it all the way down when I'm moving and changing gear; I do push it to the floor, as recommended, when I'm selecting a gear at rest, including reverse. I thought everyone did that!

 

If I set up a comfortable driving position, where my right leg isn't in tension on the accelerator and I can get onto the brake pedal smoothly, any attempt to get the clutch pedal to the floor has me sliding forward on the seat. Obviously, I compromise on the driving position; but why should I have to? Again, for the sake of clarity: both my legs are the same length.

1. You don't need to push the clutch pedal to the "stop", ever.
2. Do your ankles not flex?

Sorry but that is total nonsense. Do you honestly think the designers would allow the pressure plate to be overthrown by anyone daring to press the pedal to its fullest extent?

 

I don't think Skoda themselves would tell us to fully depress the pedal if it was going to compromise the pressure plate in any way.

 

Thankyou for your kind words

 

The person was complaining that their clutch released very high up, if that is the case then something is out of tolerance and not within design limits, there is nothing to be gained by depressing the clutch significantly further than the point that it disengages and there is no clutch drag, doing so with a clutch that has an abnormally high biting point will be overthrowing the diaphragm for no good reason, its not likely to break (although I have had one do so) but given the self destructing Sachs clutch diaphragms fitted to many Skodas it should be avoided.

 

The advice that you are telling others to blindly follow when selecting reverse gear was indeed good advice some 30 + years ago before VAG gearboxes had synchromesh on reverse gear.
