Replacing a metal brake line and flaring

I have a leak in the 3/16" metal brake line that leads from somewhere under the brake cylinder up front all the way back almost to the rear axle. The rearward 3 feet or so of the line is corroded and I'm hoping just to be able to replace that part of the line. I've got a piece of just straight prefab steel line that's already flared and has the hardware on it. My plan is to cut my current brake line just forward from where the corrosion is and disconnect / unscrew it at it's rearward point. Then I'll shape my new line, screw it into the rear connection and bring it forward and splice it into the existing line after flaring the existing line.

Problem is I've never flared a brake line before. It doesn't look too difficult in the videos but in all those scenarios they're putting the flare tool in a shop bench clamp and twisting things down super tight explaining that if the tool that holds the line isn't tight the flare tool will push it out of position when it's cranked down. My issue is I'll be doing this under the vehicle and won't have the advantage of leverage to get everything tight enough.

Any advice about doing this under a vehicle?

also

Any advice on how to bend this 3/16" steel tube? sand possible? bend tool?

Dont be as pussy about it

FOR FUCKS SAKE DONT PACK IT WITH SAND

Most people just bend it over your fingers but there is a snaz plier that makes super tight little bends

The $9 tool @ japmart will do 3/16 just fine

Buy this brake flaring tool. Only does 3/16Ē but well worth its weight in gold they turn out perfect every time and itís easy to use under a vehicle. Videos online on how to use it it. Eastwood sells the same one.

Thanks for all the help. I've learned a lot. After consulting with my regular mechanics I just let them do it because the whole line really needed to be replaced. As it went up through the engine compartment it just got too twisty for me. Peace of mind.

If this was the old pirate the op would of explained he needed new lines and then built his own flaring and bending tool from random shit in the shop and shown it off here. Gone are those days.
