Doesn't happen.

Dragging any brake is wrong. Use them, slow down, then don't use them. Use the front brake when you need to slow down, use the rear or both when you need a little more control. If you can't do your current descents w/o dragging the brakes the whole way down you're in over your head and need to find a mellower way down.
