I was not bleeding them, was checking to verify if the return vent was plugged in the master. I opened one at a time. So I'm guessing there was no fluid pressure pushing the piston out. Which should mean caliper is stuck most likely from corrosion. Car has been sitting in high humidity area doing nothing for 3 years. Not bad idea getting new master and calipers.
Don't like the wire with voltage. I'm not going to worry about it. Has not been an issue and will just install in the new ones.
