Please explain "pulling through an arc". The lever is always going to be pulled through an arc. Where it starts just determine where on the are it is pulled. How does 15 degrees help?"

Visualize the brake actuating arm shaft cup where it contacts the operating pin. As the clevis arm is moved from the 15 deg forward to vertical the maximum mechanical advantage will occur when the clevis reaches vertical.
