Default Re: Don't like coaster brakes?

Been thinking about this, coaster brake forward. Could rig it to advantage by having the "throw" led around a small pulley. ("dead stop it 180 degrees around and above pulley) One would double the force of the pull but would take twice the cable length moving to pull the brake as much. Am thinking lever arm but so far, that would cancel out the mechanical advantage of the pulley. Snork, I need more coffee.

OK, 2 pulleys that draw to each other and pull a lever about midway with the attaching arm connection to the chain of the brake at the end to increase the throw and keep the mechanical advantage. Would add 4X the pulling force reduce cable travel 75%. But the arm would make up for the lost travel, at least some of it.
