FESTVA SCREACHING? BRAKES?

Festiva screaching?
I have a 1993 Ford Festiva. Everyday when I leave to go to work, at
the first 2 stop signs there is a screaching sound when I use the brakes.
Then there isn't any noise after that until I come home. But not as much as
the morning. Sometime when I stop at the store there is a liitle screach
when I apply brake first time. I had brakes checked at Midas and they
couldn't find anything wrong.
ANY IDEAS???
