seized Front Caliper middle bolt/pin
No issues removing the upper and lower pad retaining pins and clip
But the middle pin/bolt with the 13mm inside bolt is frozen, seized.
(on both drivers and passengers side)
any suggestions or tips on how to remove that middle bolt/pin??

Tiny bit of heat on those flanges may help get things moving if the above hammer/punch aren't sufficient.

Leave the bolt that holds the middle bridge bolt in a few threads, and hammer on that bolt.

I had to use sandpaper and brake cleaner on mine, as it had caked on dirt and corrosion from all the street salt, and then I was able to punch it out.

I had to hammer the ****** out of it. chipped some paint, but you can always repaint calipers.

Get a longer bolt with the same thread that you don't care about and do this. A longer bolt will let you hammer with less chance of hitting the caliper and damaging the paint.

Second cut. Used BFH and inner came out. Used 1/4 punch and BFH to push the outer part out. (Man... it was in there good!!)

Wow, lol. That's one way to get it out. Did you try heat?
Try some anti seize on the new pins.

New pin/13mm bolt on top * going to source that middle pin/bolt (Unless anyone knows a brembo or aftermarket part number)
Might try to source parts locally

I just bought a small stash of them from Lexus so I could replace them at will if they ever gave me any grief. When you track your car, you get to know brake maintenance very well.
