Hey y’all, finished up my knuckles and put new pads and rotors, but this thing was neglected for quite some time by PO. The driver rotor was completely shot from the brake pad metal digging into it. I noticed only the outside pad was worn and the inside pad looked almost new. Do I need to rebuild or replace the caliper?

Can rebuild them if they are oem at least that's what I would do if you know how .
A rebuild kit (04479-60020) it available from Toyota:
For $40, it's hard to argue that replacing the calipers is the best solution, but it does depend on your resources and time.
The aftermarket pad kits are supposed to come with springs and pins, but even if they do, they're not the quality the Toyota kits are.
It's hard to tell from your photos whether the problem is the pistons or the sliding pins, or both. You won't know whether rebuilding is practical (I have no idea what your resources are) until you remove the pistons and and inspect the bores. Replacing is easier, certainly, but not the only option.
It's vital that the sliding pins allow the caliper to move freely; it it doesn't you wind up with the pad wear you have now.

If you get rebuilt ones you need to look at the pins and check under the boots on the pistons to make sure they are good rebuilds. They are easy to rebuild but it is messy.
