Thank you so much for your kind reply in this almost monologue I have here
Yes, you are absolutely Right; the added length to the brake pedal, not only makes more comfortable and safe to reach it; but also gives a more favourable leverage effect, as you accurately described above; in fact, as the pedal got the extra length, also it came out to the front a little, which allows me to move my seat one notch farther, reaching the Brake pedal safely; which makes the overall feeling of driving the car, way better.
I hope that the information and ideas I share here, could be helpful for more people.
Kind Regards.
