Unlike \bendAfter, you have to use with curly braces:
Nope, it even works without it!
So you can use \bendBefore exactly the same way you use \bendAfter
Hope this helps!

#(define (make-bend x)
(make-music 'BendAfterEvent
'delta-step x))
bend =
#(define-music-function (parser location delta) (integer?)
(make-bend (* -1 delta)))
bendBefore =
#(define-music-function (parser location argument) (integer?)
#{ \once \override BendAfter #'rotation = #'(180 -1 -1)
\bend #$argument #} )
{
c'1\bendAfter #5 e'1 d' \bendBefore #5 e'
}
%%% EDIT: I removed the braces (not needed after all)
