I'm actually in the middle of redoing my brake lines and converting to power brakes. My prop valve looks exactly like yours with that "pin" sticking out about 1/4". I've ordered the bleeder tool and its on its way. But what is the length suppose to be sticking out of the valve??

I took my sensor out of the top where the bleeder tool would install and I can see the brass components and the shuttle valve for lack of better terms and was able to move it back and forth with a flat head screwdriver, but as I did this that pin did not move and I can't seem to move it with pliers in or out...
