I was frustrated with the 75% braking limit, when playing GT3 with the
Logitech Driving Force wheel. It was not such a big issue at first. I
was able to get all golds in the license tests except Super License.
Finally, things got more difficult and I wanted 100% braking. I
discovered some problems with the 5v reference voltage supplied to the
pedals from the USB. This may affect the use of the wheel on the PC as
well.
I added a AA battery and variable resistor to bring the voltage up to
5.0v and it all works. An electrical engineer could probably show me a
transisor part to do the voltage rebulation and remove the need for the
pot.

I hope this helps,
