Here's from the Haynes manual for the Mazda 626, 1993 to 1998,
page 8-7, section 8.5, "To adjust the pedal freeplay, loosen the locknut on the
clutch pushrod. Turn the pushrod to adjust the pedal freeplay to the specified
range and retighten the locknut."

Haynes is not always accurate. Furthermore your quote concerns the clutch
pedal adjustment. There is no adjustment for clutch freeplay.

Well, that might explain it. Since this is a Miata forum and the
original poster had a Miata and nobody, including you, had mentioned
626s, I assumed we were talking about, well, Miatas. :>)

The 626 is frontwheel drive with a transverse engine. The Miata is RWD
with a longitudinal engine. So yes, the position of the clutch
cylinder is different.

Same thing here, on a 95 with 45m that was a weekend car. It squeaked a bit,
then I noticed I'd almost run out of fluid (slave cylinder leak), filled
that back up, I haven't noticed the squeak for some time now. I'd say check
your fluids and give it some time while you use it more.

cool deal--will check the slave cylinder and reservoir. thanks for
everyone's advice.

In Belgium (and most other european countries) that's already in the law.
Only "handsfree" calling is allowed.

Fine is about ? 50, that will be raised to ? 100 in April. Countries where
you really don't want to get caught are Spain (? 600), Norway (? 640) and
Poland (? 1520).

IIRC, at this moment 1 EUR = 1.2 USD?

Mmm, obviously the euro-sign is not in my character set... Replace question
marks with http://www.hegrobelgium.be/eur/sign_euro.jpg :-)
