Inability to achieve high gloss shine on left shoe.  Sudden drop of clutch 
pedal,  recovered by putting toe underneath and pulling.  Stains on carpet.

(And no - I'm _NOT_ joking about the shoe!)

Brake (Dot 4) fluid.  On a LHD car, a spur off the brake fluid reservoir.  On a 
RHD car, a tiny reservoir _behind_ the firewall in what we call the 'scuttle'.

120k to 160k miles

Clutch m/c doesn't leak outside the car.  It's inside.
