So aside from taking it apart and putting it back together again, is there anything I should specifically look for when doing that?

So I'm pretty sure I found the culprit...

Unless 2 of the inner o-ring seals are supposed to be notched? Not sure how I didn't notice this when installing...

Those piston seals should not have those cuts in them. That would explain your leaking caliper. They're supposed to retract the piston back when you get off the brakes.

Yeah, I ordered two full centric rebuild kits to have extra parts. With expedited shipping, should be here on Tuesday.

Tempted to take the other one off and apart to check and make sure it's fine. Even though it wasn't leaking any fluid.

Did the shop that powdercoated the calipers remove and install the pistons? They could have ham fisted it back in and pinched the seals.

They removed them. I got them back disassembled, greased them with the RRG and put them back together myself. There's a chance I did that, because I feel like I would have noticed that before reinstalling them :(

Was super busy over the weekend but saw your posts. Was going to say it was probably the piston seals and glad you got it figured out.. If those are original I'm interested in how they got like that. Dust boots were hard to take off without damaging, but the seals were relatively easy. All my original ones came out perfectly so I ended up not ordering any new ones.
*edit* looking at it, the place might have used pliers or some sort to try and pinch the rubber to pull it out. I don't think you caused that as I can't imagine how you'd create clean cuts like that while putting the seals in.

In the end it doesn't matter either way, but honestly, I'm leaning on it was something I did during the rebuild. I greased all 8 of the seals, and I would have noticed something like that. It's possible they may have nicked them and the tears just weren't that prominent, but they definitely didn't look like that when I installed them.
