Power Glitch on applying brakes

In My acura integra when I apply brakes, I see a power glitch
The power comes back right up, the stereo, lights,etc come back
right back. Any ideas what the problem could be.
Is it the alternator/battery? The car does start up fine each and everytime.

sounds like the brake switch is grounding out or the pedal is hitting something and causing it to ground it out
