Here is a thought, for the less able amongst us (1 armed MTBers, not that I've ever seen any).
ONE BRAKE LEVER pulls both FRONT & REAR Hydraulic Calipers:
(Made possible with HOSE SPLITTER/T PIECE, held on with hose olive unions as usual)
1 HYDRAULIC BRAKE LEVER
2 HYDRAULIC CALIPERs WITH HOSES
1 HYDRAULIC HOSE SPLITTER (Looks like "Triangle" or "T")
I wonder if the lever FORCE/FEEL is affected? That 1 lever pulling all those Calipers (x2) ? Or "IF" you ever needed to bleed
your brake(s), this might be more ackward.
Or perhaps in real life there is little or negliable difference in stopping distance, for an already disabled person in comparison to just using 1 brake. But since brake bias can't be adjusted by left & right when riding, presume stopping distance will always greater, in comparison to fully able persons of comparative size (Even despite the disabled person weighing less because missing one arm, eg Gravity/Momentum: Lesser weight takes less force to stop)
