Front disc coversion problems

Well, FINALLY got a decent pedal. Bled and bled after installing and adjusting a rear prop. valve and the pedal feels ok now. Not rock hard but ok. Stops ok too.

Now, my dash brake light is on. Everything ok.....I;m guessing it's something with the distribution block throwing the switch on. It's not the e- brake switch. Already checked that.

Any ideas?
Yep the valve has a switch to warn of fluid loss front or rear. there is a way to get it centered again. Should be details in a service manual.
