I tried the same thing, GDA, with the same result. I gave up moved the brake back to where it was. I tried a few other alternatives, but none were successful. My solution came from Lamonster's RIP floor boards, which change your foot position in relation to the pedal. They are just brilliant, and for me, well worth the price. I can't tell you if they are an option on the F3S, though.
