2015 brake caliper seized

[Kbike230]

Hello!
I'm having an issue replacing the front calipers on my 2015 4Runner Trail Prem. I originally sourced my parts from the local Auto Zone however, once I tried to bolt on my new parts the caliper bracket bolt did not fit. It seems there is a difference in calipers made after 6/2015. My truck has a manufacture date of 6/2015 which has me confused on which part number to buy. The OEM caliper casting has a 14WB and the Auto Zone one has a 14WA. Using parts.olathetoyota.com they have both parts listed but there's no description on which casting mark either part number carries. If anyone knows which one I need it would be greatly appreciated.

Here is some photos. I can't figure out how to upload directly.

Try your local NAPA store.

If you are at all mechanically inclined and familiar with safely working on brakes, I would not recommend replacing your OEM calipers with ones from the part store. Instead, order an OEM rebuild kit from the stealership or online.

You must have gotten one of the 1st models with the new Calipers with the 14WB casting on your OEMs.

I just put Centric 5th gen calipers on my 4th gen. Only have about 3k mileson them though. No issues so far.
FYI, I've had good luck with Power Stop pads and rotors on my 5th gen and 4th gen.
Oh and always bed your brake pads in.

Why not? Ive 4th gen 4Runner that is notorious for seizing front brakes. I replaced both with CarQuest calipers 5 years ago. No issues. Best part besides price is lifetime warranty vs OEM’s one year.
