replacement pads work the same. if your pads are too worn, they will NOT replace them for free under the TSIB. The TSIB works like the warranty does--items in need of replacement due to normal wear and tear are not covered.
Just an FYI...
It really depends on the dealer. I just took my '08 in for another issue, (broken wheel and destroyed tire from road debris, but that's another story!), and while it was there, I asked if they could do the brake TSB. My car has a little over 13k on the clock, but they warranted the pads anyway. They did advise that I have the rotors replaced, but I opted to pass on that, at least at the dealer.
Well, of course they did. 13,000 mi on your brake pads is not near the normal replacement time.
Makes sense, but it still seemed like a lot of miles for them to do the TSB fix... and as some have found, a few dealers will not do it with that many miles. I drive pretty aggressively, and I'm sure that my pads were pretty worn.
