Changing brake fluid without bleeding

The message from "Biggleswade" contains these words:

Not as good as proper penetrating oil.

Also support the spanner so it's trying to turn at right angles to the nipple. A force applied at the wrong angle is far more likely to break it since they're hollow.

Buy a new nipple first just in case you need to drill the broken one out. Strange thing is once they are broke they often come out quite easily without the need to drill;-) smicker

The message from "Dave Plowman (News)" contains these words:

Or use a T-bar wrench.

Yup - that's the best solution. But not many socket sets seem to have them these days.

How do you get the hose out of the top if you use a T-bar? or am I missing something?

The message from "Will Reeve" contains these words:

You only use a socket to loosen 'em - once they're free you can use a spanner while you're bleeding 'em. And they don't need to be very tight at all when you've finished, either. Not a whole heap more than finger tight is enough to keep the fluid from leaking.

then you use a brake spanner which has thicker walls and a little cut out on the ring portion or i tend to cut through the pipe if i'm replacing it and find that a deep socket will go over the top whatever you do though, make sure all this lossening and tightening is done with the caliper on the car fitted and bolted up otherwise it tends to get dirty and clumsy and you don't get the proper leverage on the nut, crucial in not rounding the buggers off
