Let us know what you find.
Ripped everything apart over the holiday to find that the passenger side front caliper carrier had one frozen slide pin. It explains the one pad that went to metal with the other three at half-wear. Trying to find a good used one today to get everything put back together.
Since it was over the holidays, and I didn't have time for AB to mail me anything, I bought pads and rotors at my local Autozone. They look better than the parts I got from AB the last time. And with a lifetime warranty on a $24.00 set of front pads, I think I will be money ahead.
Strange squealing noise has not been solved unless it was water boiling between the rotor and pad. I have gotten used to the shuttle valve clicking after the car has been shut off.
