Wondering if brake bleeder screws can be blown through? It seems plugged, so I took it off my bike and hooked vaccum bleeder line to it and still no air is passing through. Is the screw bad?

open 1 of them and squezze the brake lever..then you will know if it is plugged.You can't blow backwards in a closed system..no where for the air to travel.If you open up the reservoir and then blow air thru the bleed screw then your oil should splatter all over you and whatever is around,,lol
I'm talking about the bordered screw being completely out, holding it in my hand and trying to pass air through it. I can't get any through

Quite common for them to plug up (on cars anyways).
Take a drill bit to the outer hole of the bleeder and twist it by hand to draw out any crud. On the other side of the bleeder (the end that screws into the caliper) below the tapered end you'll see a cross drilled hole that often gets plugged flush which makes it difficult to see. Drill out the crud, again twisting the bit by hand until the hole is cleared.

Let it soak in a cap of wd40 or brake fluid and it will clean up like snomo says or replace it.
