HELP ME: HAD to cut rear hard brake line and need help with what my options are

A simple stainless steel brake line upgrade turned into me having to cut and “flare” the brake line since I couldn’t get the 10mm nut loose.

Anyways the line is cut and I cannot do a good double flare on these lines. I practiced with some copper lines and they come out excellent. When I cut the Tacoma lines the hole is not a round hole and yes I tried de burring it already.

I’m done trying with flaring, at this point I want to know if anyone here can tell me how to REPLACE this rear brake hardline. How hard is it to replace the rear lines? Or should I just call a damn tow truck and pay thousands lol.

here is a picture of my “flare”. My other ones came out looking like single flares.

 

2 options.

Make a whole new line from NiCopp.
Or buy a new brake line from Toyota.

Why do almost ZERO videos exist on YouTube on replacing these brake hard lines lol! Is it That hard?

 

I’d say make your own outa softer material..I’m not too sure you could “fish” a Toyota replacement in their with the bed on etc

 

The nicopp lines are easier to flare but you should def be able to do it on the steel ones as well, even with a cheap tool. You need to make sure the cut is square/perpendicular to an inch or so of straight tube where your tool will clamp, the tube is still round (not crushed), no burrs on the ID, and most tools recommend a light chamfer on the OD. Sometimes I have found it easier to cut with a dremel or angle grinder cutoff wheel than a tubing cutter depending on the line/space.

I would recommend working to get a good flare and splicing to the OEM hard line before replacing the whole section. From your picture it looks like you didn't have a straight section of hose within your flaring tool or you didn't clamp it tight enough and it slipped on the lines.
