Much like martin417's team, we had a simple brake system designed for the winch that ran our forklift for our 2008 season. We used the FP motor, but had a terrible problem with it coming back down with the huge ball weighing it down.
We ended up taking some spare tire tread for our AM performance wheels and wrapping it around the drum that winched that was actuated by rotating a servo. Very simple, yet very effective.
