Ian,
The most likely cause of your clutch slave cylinder
failure was water content in the brake fluid.
Unfortunately brake fluid pulls water right out of the
air... get enough water in there... add a freeze and
you have a problem.
I routinely drain and refill the brake fluid (per
Peugeot specs) once a year. I also ONLY use Castrol
GTLMA brake fluid (LMA = Low Moisture Activity). This
too is a Peugeot spec (see the yellow tag on the
firewall next to the brake booster). Over the 30+
years of working on Peugeots, I've found that using
ANYTHING else results in premature seal failure...
My two cents worth...
