This post is only for advanced fabricators that have the skill, knowledge, and experience to do this properly (!).
If you cannot relocate the pedal rod connection point without causing a linkage bind condition, there IS one more alternate option that some do not consider in these discussions, and that is to cut the pedal and lengthen it. This should only be done with a very powerful TIG / Stick welder and very experienced welding skills...
This can effectively increase the mechanical brake pedal ratio considerably, but will make the pad of the pedal lower which poses some limitations as to how far you can go.
