I have been doing my own brakes for years. I have had some that were not easy to keep from squealing but this one has me wanting to get rid of the car. We have a 2008 Dodge Magnum R/T package. Roughly 38K miles on the car. When the car reached around 10K miles the rear passenger wheel would squeal when you applied the brake. Rotor surface was smooth as glass. I took off the rear rotors only and had them turned. Problem went away for about 5K miles. Then the fronts started squealing. I replaced the fronts because hte factory did not leave any material to be turned and noted that Dodge glued the pads to the calipers like they would never need to come off. Problem went away for a little while. Then it came back with a vengeance. I replaced the pad material on the fronts with ThermoQuiet pads from Raybestos. Problem is coming back again and now I cannot tell which end of the car it is even coming from because it it so loud. My wife drives this car very carefully. My thought is she is polishing the rotors too smooth and this is our source of noise.
We are at the point of squealing again and I am at my wits end with this. If I light foot it, no noise. If I stop like I think it should be stopped, not killing it, the noise is there. If I stop very quickly about 3 to 5 times in a row the noise is gone for a little while until the pads cool and then it is back even if I am on the same journey.
