The previous suggestion of a 555 timer (or the 7555, or any of the
derivitives) could work.  Even easier, a simple R/C network that shorts
with a resistor when you hit the brake, and re-charges through another
resistor when you release.  The cap won't discharge all the way for short
braking spells, and if it does, you time the R/C network to give you 5-6
seconds max.

I prolly could put a schematic together... just not today or tomorrow...
being hammered at work... in fact, I shouldn't be reading my 291 messages
this morning :)
