No parking brake?

Anyways I figured this all out after needlessly replacing a caliper that ended with the same results as before. Looked into it and it was too simple

I thought the parking brake was purely mechanical.

I never understood why the calipers have two bleed valves. Ironically, the passenger's side is the only one I attempted to bleed with the bottom valve out of curiosity. I still bled both rears with the top screw but hopefully it's coincidence that the passenger's side isn't working. I've probably bled the whole system 5 times now with a Motive pressure bleeder and the traditional 2-person method and no luck.
