Corrosion between the line and the nuts also mean the lines are compromised
at that point. Probably time to replace them. When using heat to loosen
things up you really need oxy-acetylene. The goal is to get that nut hot
enough to loosen from the line fast enough that the major part doesn't not
have time to get hot. If you don't know when the master was last replaced it
is probably time to replace that also regardless of how well you think it
works now.   They often fail suddenly.

Subject: Next question - Removing 35 yr old brake lines from MC. :-/

Well, since the brake hoses actually have a plastic ring around them that
says 77, I'm betting the metal lines are original too on my Westy. So I know
the nuts are frozen onto the brake hose ends of the metal lines, and I had
to actually spin the whole caliper/ hose assembly to get it off the metal
lines. I am just imagining what the other end is going to be like at the MC.
My thought is to use PB Blaster and soak the hell out of it for a few days,
then apply some heat from my propane torch. Can I do this without destroying
the MC? It appears to be working fine; I'd hate to ruin it just to get the
metal brake lines off. Of course some will say, just replace it anyway :-)
Thanks, Courtney
