It's really used more for cars.
VERY FUNNY

( could be true though cuz I know zilch about cars)
With gliders a brake will stop the rotation of the prop when power is off allowing a FOLDING prop to fold. Soft brake option is less stressful on the prop roots as is soft start.
If you are using a NONFOLDING prop let it spin for less drag. (won't be a big difference though)
Minnflyer was being serious. Usually the only r/c that uses brakes on an esc is cars.

Minnflyer is a GREAT recourse. Extremely helpful, knowledgable and an all around nice guy.
None of the above are good reasons to stop giving him an occasional hard time though

I send all my new guys to his stickies.
