There's a minor discussion going on in Miataville about differences in
brake fluid. It's being said that some brake fluid is more compressible
than others which makes it less desirable.

Is this really true?  I always thought that brake fluid was not compressible
period. Isn't that the whole point behind hydraulic brakes?  It seems to
me that the only thing that would make it compressible would be if it
began to boil.  I could see differences in brake fluid being due to the
relative resistance to boiling.

I'm confuzzzled. (I thought I understood physics. Guess not.)
