What a great piece of information.
I now have my Spit and Hurri brakes mapped to my rudder pedal brakes and they also show up on the settings screen in the sim.

Here is what I did:
Locate the userconfig.ini file in: "mydocuments\1csoftclub\il-2 sturmovik cliffs of dover" folder.
Add the following two lines (in blue) to the configuser.ini file at the bottom of the page.

[HotKey pilotMove]
Joystick+AXE_Z=-1throttle
Joystick2+AXE_Y=1brakesrt
Joystick1+AXE_Y=1elevator
Joystick2+AXE_X=1brakeslt
Joystick1+AXE_X=1aileron
Control Joystick2+AXE_X=1brakes
Control Joystick2+AXE_Y=1brakes

Then I mapped a Control key on the keyboard to be pressed when applying the brake pedals. I now have both left and right working independently from each other than just the "b" brakes in the default. I also mapped the Control key to my Cougar Hotas speed brake control so that I just depress the key while applying the brake pedals.

Also note, the 1brakesrt and 1brakeslt above assigned to the same rudder pedal brakes - they also work. You just don't depress the Control key when you want these to work when flying an Axis aircraft.

NOTE: make sure you remark out or remove the original line "b" for the brakes as in the default.

Hope this makes sense.
cheers
