(someone really should resize those pics)
Yeah, I have seen that one. That machine is pure art. But I don't really see many advantages over a brake pedal construction with the pump in the neighborhood of the original location.
Someone at another forum came with a 'reversed' solution like this one
. I like it. Harder to kill the brake pedal when dumping the bike.
I'll investigate that 'mirrored mount'. If that's too complicated, I will just make a bracket which moves the pivot point closer to the frame since I see no real disadvantage in having a slightly longer brakepedal-to-pivot distance as long as the lever ratio stays correct. And in the neighborhood of the original location the brake pump is tucked away nicely.
Anyway, back to the drawing, ehm, cardboard:
