I had the same issue with my 2012 SRT. I tried a bunch of different stuff after replacing the pads with the same brembo pads that come stock. After talking to a bunch of people about the issue, I came to the conclusion that the brembo pads have terrible squeaking after replacing and horrible brake dust (I'm sure you already knew that...). I went to www.blackopsautoworks.com
and got a set of pads off of there. I forget the name, but they only have a few different types of pads. Everything on that website is sold because of other SRT guys input so next time you need replacement check them out! I hope this helps!
