I was wondering about adding my own answer to:
How to fix a seized V-Brake arm?
Chris H's answer pretty much nailed it, but some of the comments were helpful as well and I thought it might be useful to collect all the points together. On the other hand experienced members of the site are probably thinking this was such a straightforward question as to be hardly worth the fuss.
So my question is should I add my own answer as a summary of the advice received and how the repair went?
