I got my car back yesterday. The rear pads are in and the wheels are shiny clean. I should know in about five days whether that strange smell is the smoke that's been blown up my ass seeping out, or if they really fixed the problem.
As for the part number, I was hesitant to post it fearing that another lie from the Mazda f***ers would make me look like a jackass. That being said, I have a theory...I was told that the factory began installing pads of a different composition in Feb./march, now it could be that since these pads will be on all 3's in the future they did not bother to change the part number. Trust me on this, when it comes to people at the dealerships, simple is always best.
That being said, if the dust is still present in a week, then Mazda owns me a good sum of money, since this was the final repair attempt under the GA lemon law.
Now, I don't doubt that other dealers in the US and Canada have fallen back on their official Mazda corporate bullshit manual when answering questions about your cars. I also don't harbor any bad feelings for anyone who thinks that I am wrong, it may turn out that I have once again believed their lies. Only time will tell.
