Squeaky Brakes - Normal?

My brakes have been squeaky since I brought my GL home 3 1/2 years ago. FREQUENT requests to have the dealer fix it have gone nowhere, they have said it’s “normal” (trust me it’s not a normal sound!!) that they don’t hear it, etc., etc.



My question: IS IT NORMAL??? If not, HOW do I get it fixed?? It drives me crazy, esp. in the summer w/the windows down.



Any help would be greatly appreciated!!!
