on the FC once you get the rears bled, its actually kind of hard to bleed the front, i've had good luck doing it backwards, IE front first, and then rear. there are also two ports on the rear calipers, and you need to bleed BOTH

 

I've bled both ports on rear caliper once I saw it in the fsm. But bleeding them backwards? I guess, I'm willing to try anything at this point...
