What Jeremy says also misses the connection between low mechanical advantage (necessitating more grip strength) and arm/hand fatigue. There's a reason why systems only requiring one finger braking are highly prized for off road riding, same would go for any situation in which a rider is braking

It may help to clarify a few things here, and define terms. Braking "power" is a tricky term, but for the purposes of my post we could define it as amount of normal force applied by the brake pad to the rim. This is dependent on the mechanical advantage of the braking system (brake, cables,
