Narrative:

Near departure time I was on the radio concluding a discussion with dispatch about our route when the ground man called up and asked for 'brakes released.' I released the parking brake but then realized we didn't have push clearance and reset the brakes. Then when we did get push clearance I forgot that I reset the brakes and told the ground, cleared to push following aircraft on our tail. After about 5-7 mins we began push. Prior to aircraft movement, we heard a bang from the nosewheel well and realized the brakes were still parked. I called mia flight and debriefed him and then later spoke with dfw flight and debriefed with him as well, due to the fact that I am dfw based.
