How hard is it to replace a hard brake line? Almost rounded one.
Torquing the RF brake hose to the line the fitting started to round... I don't have flare wrenches, guess I should get some.
It's perfectly fine for now... but if it ever gets to the point that I have to replace one, is it hard?
The RF line looks like it runs alont the crossmember then up to the ABS distribution block or whatever it is.
Anyone ever swap one out?

you shouldn't be swapping lines that often, so just leave it alone as lone as you can. However, a 13mm flare wrench is certainly a good investment.
I don't it would be too hard to snake a new line through there. You could get one pre-bent from GM, or likely get one approx long enough at NAPA, then bend it yourself and put the right ends on it. I think it is ISO bubble at the EBTCM, but a normal flare at the rubber line.

David... first off... how tight do you make that fitting? Is there any rule of thumb like finger tight then 1/4 turn or something like that? Normally you can feel them check up, but this time I rounded one face.
Second, Could you cut off the flared end, get a new end fitting, then re-flare the line?

You normally wont have to replace the entire line. Cut off the end and Flare it add a connector and new end. It depends on how much line is visable. Using the flare tool in place on the car is a pain for the mechanical screw types but it can be done.

Just remember to add the new nut to the line before flaring. It seems obvious but I have had to cut off flared ends and reflare them more than once on different projects because I forgot the nut first.

and make sure you get the RIGHT end, as there are a bunch of differents styles.
I just tighten them as hard as I can with normal had wrenches. They are flare fittings, so the "junction" is the seal, not the "threads". In other words, it isn't like putting in an oil drain plug where the threads must seal.

Performance Nut had to replace a metric flare nut on his C4. If you
find yourself in a position where it is necessary to repair a line, his
thread may have some helpful information for you.
Frustrated beyond belief
