Not sure how that would work as 4 of the shims have the black on one side and the other 4 have it on the other side.
So I can have the black coating against the back of the pad with the first shim, and stainless on the other side so that the stainless of the second shim are together and then the black coating of that 2nd shim is against the caliper piston or ears.
Or I can have the stainless against the back of the pad with the first shim, and the black coating on the other side so that the black coating of the second shim are together and then the stainless of that 2nd shim is against the caliper piston or ears.
Intuition suggests the first scenario where there is the stainless between the two shims so they are free to move easier, but who knows.
These are aftermarket pads so the Toyota shims aren't exactly the same and have only one on each pad.
