hey guys I got the new brake TSB done today, at least I think. My brakes were squealing like a bitch and I took it in and they replaced the front brake pades. Now my question is on the part number. The part number they used today was F1Y2-33-23Z. The brake pad replacement on the new TSB is F1Y4-33-23Z. Is that number different for different regions or is this the old TSB part number?

F1Y2-33-23Z is the part number from the older TSB.

I do not know if that was just an administrative change or if the pads are different, if the squealing is gone why worry? Contact Mazda USA or make a new thread " Part Number Question". There are some people here with Mazda connections.

I believe there was an actual physical change (not just administrative). A lot of people still had squealing after the first TSB....I have had the new one recently....and still no squealing.
