I have heard that as well. You can avoid that possibility by not
pushing the pedal past the normal stopping point, just use short
strokes. This is a bit of a hassle if you are using the 2 person
method and need to coordinate the wrench and the brake pedal, but
should be a cinch with the speed bleeders since they have a built-in
check valve. A block of wood could be placed under the brake pedal if
you want to make absolutely sure you don't go beyond that point.
