IF I GUESSED YOUR INFO RIGHT....THIS IN THE LINK IS A COMMON DENOMINATOR FOR THE HEAD AND TAIL LIGHTS

http://shop.advanceautoparts.com/webapp/wcs/stores/servlet/product_headlamp-switch-acdelco_3965708-p?searchTerm=headlight+switch

SEE IF IT IS RECEIVING POWER FROM THE BATTERY--A VOLTMETER OR TEST LIGHT WOULD HELP

IF IT IS NOT GETTING POWER (GUESSING THERE IS A BIG HEAVY WIRE FEEDING THE SWITCH), GO BACK TOWARDS THE BATTERY LOOKING FOR A BROKEN OR LOOSE WIRE--MAYBE A BURNED FUSIBLE LINK OR FUSE

THIS SWITCH PROBABLY HAS NOTHING TO DO WITH THE BRAKE LAMPS---BUT IT MAY BE FED FROM THE SAME SOURCE

BELOW IS AN EXAMPLE OF A GOOD OLE TEST LIGHT IN USE! (TESTING A FUSE)
