I understand what your saying im only an enigneering student but I did make it to staticts, dynamics, and physics. You are saying is that by lengthing the front brake arms you trade force for distance. Simple mechanics, Like using a pully set up. You have a longer arm so you have more torque but you have to increase the distance in pedal throw.
just out of curiosity what feild of engineering were you in?
