Indeed. I want the lower half of this brake combined with a parallelogram linkage to drive it, à la Campag Delta. Inherently symmetrical, albeit doing nothing to address the problem of getting the rising rate at the right point in the travel.

Oh, and a Mavic SSC style leaf spring, much neater than that bit of bent wire.

As we should be getting master cylinders in STI/Doubletap levers in a year or two, an hydraulic actuator would be a step up from any kind of linkage, and we'll be right back to the late lamented Magura HS77

Why doesn't someone just make a cable actuated hydraulic brake, the resivoir / actuator could be really small and mounted on the brake. You could then use all brakes / shifter combinations. Wow design idea for the day - can I be bothered firing solidworks up???
