I watched my boss lock up his rear wheel because of a tube setup like that. If the brake fluid gets hot and expands, there is no where for it to go other than to pressurize the system and push the caliper piston out which makes it drag which makes it hotter so you get a positive feedback loop, until lock. Or as the pad wears the pistons retract too far because more fluid cant be pulled into the system because of the vacuum.  Thats why the caps of reservoirs have those funky rubber inserts to expand and contract with the system.

Hmm.  I wonder if I can come up with enough of a loop or extra space or something else.  I could go 3X, 5x or 10x on length maybe.  I'm mainly trying to avoid hanging a huge reservoir somewhere on the frame.   One option I considered is hanging the reservoir somewhere under the seat where it's visible, but not in such a profound space.  Having the M/C is a lot of visual clutter, since it seems like most vintage choppers run a drum.

Maybe you could use a section of flexible rubber tubing ...

This is the other setup I was referring to. I could always go with a more fashionable reservoir, and one that’s smaller.

What about a cable actuated Master cylinder? then you would have more options for placement.

or how about a Master cylinder with an incorporated reservoir?,  you could probably repurpose what you have into something like this. and mount it low on your frame to clean the "triangle" thing up.
