Re: 1997 Crown Vic rear brake lines
UPDATE! The dealer made the repair with a flaring tool. This should have been done from the start.
I contacted the NHTSA and they told me that it is ILLEGAL to use compression fittings on ANY hydraulic brake line. They are OK on air brakes, because if they fail,the air brakes apply with no pressure.
Thanks Fonz for replying, it's a shame no one else would.
