Yep...piston wasn't all the way in.

I really need to invest in one of those piston spreader tools
...and yes, that's a bunch of dirt in there that I've now cleaned up.

Anyway, the metal piece that sits on top of the rubber boot came off while getting the piston back in. What a PITA. I had to get the metal piece re-positioned EXACTLY and then slip the new pad in.

So...new caliper??? I thought you could just rebuild these things with a caliper rebuild kit.
