No! Thank the maker, I'm not that boneheaded! But this is news to me, I've
always been told/read that the Central Hydraulic System provides the "power"
for the steering, brakes, & clutch. Your comment is the first I'd seen on 
the list that suggests the clutch master and slave cylinders share the same
fluidic circuit as the brakes & the brake master cylinder.

So, there's no relation between the failure of the steering/hydraulic pump,
and the loss of clutch action?

See, and back the previous remark, how come people say that when the clutch
master cylinder starts to leak inside the passenger compartment, they find
*Pentosin* on their floorboards and/or their shoes?

Steve, I hope you don't mind me sending this back to the list for more comments!
