you'll have to make sure that all pot axes "point" into the right
direction. Check your brake pot, it should have three metal soldering
stations, and only two of them have a wire soldered to them.

Take a short piece of wire, solder it onto the empty pot soldering
station, leave the "middle" pot wire alone and unplug the other wire
where it goes into the connector on the pedal base.

Plug in the end of the newly attached wire into the connector where
the "old" wire went into, recalibrate and enjoy.

If things don't work as expected simply unplug the new wire and stick
the old wire back in.

HTH, uwe

PS: This procedure worked on my GAMEPORT tsw, YMMV if you use the USB
model.
