I don't have the score handy, but this is how you tell the difference.
A Passacaglia is a piece that is built over a repeating bass line.  A
chaconne is a piece that is built over a repeating chord progression.  I
would have to look at the Brahms as I am not so familiar with it as to call
it off the top of my head, but if you have the score handy, that's how you
tell.
