I use a USB Saitek X36 and the CH Products Pro Rudder Pedals.I've been trying to fix this toe brake problem for months.No matter what I do, it always says "brakes" or "differencial brakes" and my feet arent even on the rudder pedals. I have no idea how to fix this, except not enable my rudder pedal to act as brakes. Any suggestions?

I have exactly the same setup and don't have the problem you mention, wonder if it is spikes from the pedals?I have a registered version of FSUIPC and calibrate both the pedals and X36 through this, I also enable the 'spike eliminator' (or whatever it is called) in FSUIPC.Two things I would suggest that may help.Whatever you use to calibrate your hardware, set a little null zone for the start of the toe brakes.Make sure the Saitek rudder is not still assigned in FS, that can sure make problems :-)Best of luck.
