Mower,
Never noticed it until I read this thread, my brakes were also sticking. Heres what fixed them for me. I'd recommend reading the entire thread to make sure thats what your experiencing and then see post #27 for the fix. This fix is also mentioned in the A-10C FAQ's.
It fixed the sticking brakes for me:
