The wrench wasn't nearly as helpful as the tubing bender. I was able to make the tight 180°with the tubing bender, I also was able to invent a very cool way to duplicate an existing pipe and I took pictures!
Of course that will be great once tap a talk allows posting photos!
For now I describe;
I put the old pipe into the 1/4" groove of the tubing bender, I slide the tool until it is stuck in the corner of the existing bend, then I put the new pipe into the 3/16 groove and bend the tubing! It's precise within mm or two: amazing.
It takes a bit to get the geometry figured out because the bender only works one way but I was able to use the bender to get the very tight u-turn worked out for the end of the left brake line.
Note the tape at the bottom: I was taping the new to the old to keep them perfectly parallel. If you do the same, realize because of the bends, sometimes you need them to be lined up vertically such as this photo but sometimes horizontally, basically whichever makes the length work out; you must arrange such that neither tube is "taking the inside track".
Reminder! Don't forget to install fitting BEFORE making your flare!
I got as far as putting the flare tool on before I realized! The last length is so short it would be hard to cut off to re-do. I would use a Dremel to cut the flare off but I would be concerned the tool might not grip the already squished tube
