Do you have any evidence to demonstrate that annual brake fluid changes
increase the longevity of brake systems?

I know 3k miles engine oil changes also do not hurt and are not expensive.
But I think most people here agree for the typical driver that's way more
oil changes than are necessary.

For the record, the 91 Civic's maintenance schedule dictates brake fluid
changes every 30k miles or 2 years, whichever comes first.

good question. i'm going on the advice of a polymer chemist i know and
my subsequent experience of changing my own fluid regularly, but i don't
have hard data for you.
