I have 15K miles on my car, it's never been tracked and the brakes are driving me insane! The squealing occurs when I apply light brake pressure. It's gotten so bad that I have to brake very late approaching a stop sign, red light, etc which is becoming a hazzard. Think of nails on a chalk board x5. I took the car to the dealer and it squeked all the way over on my trip when applied. 4 hours later they said they didn't find anything wrong and couldn't hear anything

, are you nuts? Deaf? So when I left the dealer, to my suprise there was no squeking at the first stop, but you guessed it, the squeals were comin on a full blast after that. Please help me, somebody help me! I swear, I'm not going crazy!(The technicians beg to differ)

Is there somekind of simple remedy or product I can do or buy to prevent this?
