That might explain things, although it shouldn't have worked before either.
CBQ creates default pfifo qdiscs for its leaves, these use a limit of txqueuelen or 1 if it is zero. So even small bursts will cause drops. Do things improve if you set txqueuelen to a larger value *before* configuring the qdiscs?
Another thing is that CBQ on bond will probably not work properly at all, it needs a real device since it measures the timing between dequeue events for idle time estimation. On software devices this doesn't work.
