Surely you mean the speed brakes, not the parking brake . because seen the position , the form of the knob and the mechanism to activate ( turn instead of up/down movement) I would find this highly improbable. But Ok there might be a first in everything.
Nope I mean park brakes and not just a first, its happened on at least 5 occasions. On an A320 the park brake is next to the flap handle.
