Why is my 2009 Toyota Corolla breaks squealing?

[ConcernedDriver]

I went to the dealership twice and they could not figure it out. It has 16,000 miles on it. It's not constantly squealing, just after i have been driving for a while. They cleaned it and then test drove it for 3 miles and then said " all fixed" but sure enough by the time i got home which is about 14 miles away is was squealing again. Any suggestions?
