Normally, there should be about 1/2 inch between the resting position of

It is actually there to guarantee that the piston can fully return to
its stop (circlip usually) and fully uncover the compensating port
allowing pressure in the slave cylinder and lines to release and fluid
to return to the master cylinder reservoir. If this does not happen, the
system may pump up and slave cylinder will not return thus not applying
or only partially applying the clutch. The most common symptom of this,
apart from a lack of pedal clearance, is a clutch that slips.

Also, it is wise not to dick with the pedal height adjustment as you may
end up with more MC travel than previously existed. That can result in a
torn or damaged primary seal if the piston is now traveling over an
unworn part of the cylinder or, worse, a part of the cylinder that has
corrosion buildup on the unworn part.

Frankly, if Roger needs to find out how to do the job from advice here,
he'd be well advised to hand the task over to someone with a clue. This
is basic stuff, hardly high tech, and he's *struggling*.


The poor lad reminds me of the Irisnman I shared the house with in
Zambia. Anything more complex than a retractable ball-point pen had
him totally flummoxed. To keep his level of frustration below the
point of "blowing smoke" he was restricted to using Bic stick pens
(pencils were no good because a pencil sharpener was beyond his level
of comprehension)

Yep, had the same experience in Indonesia - with a South African
co-worker what's more.


Mad Roger a écritÂ*:
Need help figuring out what to MEASURE when adjusting a self-adjusting
clutch pedal bolt.

I've adjusted the bolt all the way in, half way, and all the way out:
http://www.bild.me/bild.php?file=8057083bolt2.jpg

No matter whether I adjust the bolt all the way inside the clutch pedal
(turning it CCW facing the pedal like a foot would).

Or if I turn the adjusting bolt all the way out of the clutch pedal
(turning it CW).
Or halfway between...

I don't feel any "slop" anywhere (e.g., between the rounded tip and the
master cylinder piston cup). The *feel* of the clutch pedal engagement
changes drastically between all the way in and all the way out though.

But clutch pedal feel is not the question (mainly because I don't know
how
it "should" feel). So the question is only about what to measure, and
how.

The question is only about WHAT to measure with a ruler and how to
measure
it.
