Thanks. I'll try the vice grips and see what happens. Right now I'm a little worried that I might not be able to get the hard line tight enough after replacing the rubber lines because of the rounding and have no alternative than to perform a brake line repair job , such as splicing another end to the hard line. Never tried that and really don't want to either.
