rear break bleeder screws keep snapping

[meohmy01]

i have snapped three bleeder vavles off of my rear breaks. what's the trick to getting these things off? anyone else have the same problem?

U usually spray it down with penetrating oil and then go at them with Vise Grips.

i wire brushed all of the rust off. i heated it up. then sprayed pb on it several times and they still just snap right off. bleeder valves off of three different cars. anyone know what the part is that has the bleeder valve on it? just in case i end up raplaceing it i'd liek to know what it's called

the part called "Wheel cylinder", but some autoparts stores call it diff. i call it rear drum brake cylinder.
one of the bleeder valve snaped on my old car. i just said f*** that. so i left it a lone.
