I sure hope not, as I'm using 'cupranickel' copper alloy lines in part of my
brake system. According to the company I bought them from--yeah, I
know--the alloy is not susceptible to work hardening. Supposedly, these
lines are used by Aston Martin, I think Volvo and some others.
I'm guilty of buying a lot of tricky things--tools, especially--that look
like great ideas, but often end up on the shelf, never used. But, Doug's
bleeder extension was about the best $30 I ever spent.
