I need help - car people or mechanics!!!!!

OK I do a lot of my own work on my car. its a 2008 dodge avenger. My brakes have been squealing ever since I bought the car but recently its been getting worse. I've replaced the front brake pads with a ceramic pad thinking that may help but it didn't. And it only squeals if I press on the brake lightly. I've tried to take it to a mechanic but every time they get in it, the damn thing doesn't make a noise. I've tried to apply a brake lube to all my brakes including the pads in the rear brake drums and it only seemed to make the squealing worse. its p*ssing me off. The car is only a year old and its doing this sh*t. if someone has a suggestion, I will listen cause I'm desperate.
