CH yoke/pedals and braking

I've had a new CH USB yoke and pedals now for several weeks, but I still can't get the brakes to work correctly. Actually the brakes work fine (from the keyboard or from a button on the yoke) until I use a toe brake, and then neither the keyboard (period) nor the yoke button work any longer. I have to use the hand brake to stop the aircraft. If I reset the flight, they work again until I use a toe brake. Is that the only way to stop a real aircraft on the ground--by applying both the toe brakes?I've searched for this topic and have found nothing.Any help much appreciated!ed gates
