Hello fellow Porschephiles,

I am about to replace my front wheel bearings in my 911 and will probably need to bleed the brake lines again since I am quite sure that "plugging the lines" after caliper removal will introdude some air into the system (what the hey do you plug 'em w/ anyways?). I know one of my bleeder valves is somewhat rounded off I figured I'd go ahead and replace this while I'm in there. So two questions:

1) I am assuming that turning the valve open to it's stop will then allow me to unscrew the rest of the valve from the caliper right? I sure don't want to snap this thing off in there and deal w/ a messy easy-out thread extraction and possible fragments of the threads in the system/caliper.

2) I use a Motive Power Bleeder (great tool BTW) to flush my hydraulic system but am wondering if I should not also go ahead and replace the front bleeder valves with speed bleeder valves for additional protection from introducing air into the system. I've heard mixed reviews on speed bleeder valves but the fronts seem to cost no more then the regular bleeder valves so I am considering this option. Any other pros or cons for using speed bleeder valves vs the regular valves?
