Well, I have studied/installed the F/H Ted's units also, ...and I sure did not see how the F/H could increase the force (--or pressure). Even with the brake spring removed, it really does not increase the force, -but moreso just reduces the effort required to depress the brake pedal. I agree with Tom that not removing that spring is a good thing. I have heard of shoes dragging on the drums due to this. It is also worth a thought to ponder if this was such a good idea, why didn't Ford actually save the money and remove that spring also?
Another thought was even if his findings are indeed legitimate, by having the 11+% additional brake pressure, what does this gain you? In the situation of a worn stamped steel brake drum, that additional force is limited by how much the drum expands. In other words, once you have reached the extended length of the mechanical mechanisms, you are done anyway, -so having 11% more pressure is of no value in my mind if the system is already bottomed out. With cast iron drums, I can repeatedly lock-up the drums with a stock braking system, so that tells me that I can exert plenty enough braking force without the F/H Ted kit, ...so I am unsure exactly what 11% more force is going to do to assist in braking.
Mike, I like your analogies, ...especially the one with the crowbar & spokes!!
