Prior to them replacing the pads, the dealer tried all of the remedies posted that i could find....washingpads after each ride,,, brake clean,,,sanding/bevelling pads,,,,jumping on brakes at high speed,,,
"the squeel was not just a low moan...sounded worse then a semi's air brakes.
The proof was simple...replaced pads -- no squeel -- obviously "defective material".
I now have a 2010 rt, and at 30k+ (which is 10K more then my wifes new car) there's no way in hell I'd accept anything not working 100%...Hang in there...insist they fix the problem.
