So my brake pedal its being annoying. It keeps on flickering on all the time up to half way. I don't know any dead zone option in lfs (maybe I haven't looked hard enough) so is there a way I could use the Logitech profiler? Thanks

Can be a power failure.

Had it with my notebook and a cheap ass replacement charger.. When the notebook was on charge the pedals acted strange when the notebook was on battery it wasn't any problem. Conclusion => some power distortion on the USB port(s).

Test your wheel with a different computer if possible.

Neither LFS nor Profiler does not have any deadzone setting, you can use DxTweak2 to change it. Though obviously it's better to fix the pedals if possible xD

DFGT user here, clean your pedals. open it up and clean.

I have same problem with DFGT brake pedal. Cleaning it didn't make any changes with mine one. I think the reason is the suspension in the brake pedal - it's too loose. So I'm currently borrowing a friend of mine pedals (i guess it's borrowed for forever XD)
