I was attempting to change the brake fluid because it was due a change
(hoping this won't start a fierce debate about whether it needs
changing every two years or not!).

I stood on the pedal a few times with the engine off and nothing
happened. I will try with the engine on but I am sure that if it was
going to leak it would have done so by now.

I see. Thanks.

Thanks. I've never used one but when they've been mentioned here and
elsewhere on the 'net, people never say nice things about them.

If I were skilled, I wouldn't have broken it off! ;)

if the fluid gets changed every couple of years (as it should) then the
nipples don't get seized, so yes you were trying to do the right thing.
You can still change the fluid without touching the nipple. You will need
to release the caliper from its mounting bolts (having slackened the brake
hose first) then loosen the hose a bit more and press in the caliper piston,
fluid should come out of the loosened joint, keep the piston pressed in and
pump through fresh fluid, with the pedal pressed down tighten the hose,
refit the caliper and final tighten the hose, press the pedal a few times to
push the piston back out.
