Don't brake off any tube nuts or adjusters in the cylinders...
If they give you any trouble just clip the line , remove the cylinder and work on it on the bench, plenty of penetrating oil, and some heat if necessary.
A couple tools that make brake works simpler is a 'Flare Nut Wrench" they grip much better on a tube nut than an open end wrench.

And then if that's still not enough I've had good luck getting stubborn tube nuts out with these fancy vice grip pliers.
