97 Olds 88 - relay clicking when brake is depressed

I have a 97 Olds 88, 105k on it. whenever I press the brake pedal some relay(s) starts making an intermittent clicking sound from under the dash (right under ashtray/radio area)

any ideas anyone? thanks

Try to pinpoint the nosie or relay and post back for more help.

Same noise as when you use the turn signal or four way flasher?
