Brake fluid leak (weeping from a corroded section).
I won't lie: my first thought was, "is it time to sell the Suzukiclone fleet and buy a Mirage??"
I had just run a couple errands where I saw fantasically high fuel economy: 100 mpg (US) round trip in town (deserted streets - every traffic light in my favour, and lots of engine off coasting).
Maybe because I was "driving without brakes" even more than usual!
