Mate it may sound odd
but wet them up with the WD
leave for a time
get a hammer not to large and give the end of the nipple a wack straight in
like a nail.
the compression will have the tenancy to loosen it then just screw it out.
You might be surprised just how easy it will come out
that is if the hex has not already been rounded off.
only use a single hex spanner. on them.
another useful tool is an impact screw driver
you can take the driver socket of and fit normal impact socket on, good for loosening difficult fittings.

^ You could do the same and heat it. The expansion and contraction can also loosen it.

Yep, that did the trick, they were completely rounded, so had to squash them flat to get the vise grips to hold, but they came undone eventually.
Yeah, Steve, I almost went and bought some freeze spray, (which shrinks it) but didn't need it in the end.
The pedal is alot harder now but still alot of travel ? I know the non boosted system uses more leverage via the upper hole in the pedal, but it still feels like it might have a little air in there, I'm not not sure.
I'll take it for a drive tomorrow and see how it feels.

Yes heat is a wonderful tool
and heat and quenching can loosen up things that seen impossible to move
One must be mindful of the materials being worked on
the repercussions can give a result that is expensive.
A commercial hair dryer is handy for general heating.
good for fitting bearings etc
be careful with one of these they can turn a bearing blue in a very short time
When fitting the new nipples make sure to use a good anti-seize on the threads
Lub the seat with a little brake fluid

That would have been my last resort.
I put a little grease around the thread, seemed to work o.k.
Cheers guys.
