File two sides flat use vicegrips.

Should there be enough flex in the line that snipping off the end (1/4"?) won't be a problem?theghosttanker said:You don't need to replace the whole brake line, just the fitting on the end. After you get the line loose, you cut the flared end off the line, slide the fitting off, slide a new fitting on, and flare the end of the line with a flaring tool, which many auto parts stores will loan you for free. ( AutoZone) You cut the tubing with a plumber's tubing cutter, which Autozone also will loan you.
