adjustable brake pushrod?

What is the benefit of this rod being adjustable? Is this something that would keep me from having to replace my manual brake pedal with a power brake pedal when I convert my manual drums to power disks?
I installed mine when converting to a dual master cylinder on my '66. The pushrod needed to be longer than the original stocker. Added benefit is the ability to raise/lower the brake pedal for heel/toe downshifting.
