Wow..... Interesting....
I was under the impression that all calipers are just remanufactured Toyota ones with new seals and pistons and then marketed as their brand. Did Toyota by chance have two castings for the 199mm calipers? Like for two different wheel sizes like we have on our 3rd gens?
I bought Powerstop/Callahan calipers and they were indeed just painted Toyota castings.
