Before you remove the brakes, try the following...
If you look under the brake you will see that there are two springs that are used to make it "engage" when your boot releases. I have removed one of those two springs, and it seems to help with this problem, as there is less upward pressure on the heel piece in touring mode.
The way the brakes work on these two bindings (Diamar and Dynafit) is completely different.
