I had an application where an H-bridged motor required a dead stop without resistive limiting. It was destructive and entertaining. The armature would break away from the shaft about once a month...being a motor manufacturer made it rarther inconsequential. My question is breaking with PWM. Would that possibly cause some serious vibration system wide?
I have used the "bottom" of the H-bridge to stop/brake. The cautions about the supply rail increase should be headed. Also, using hte body diodes to handle the reverse current into the rail is dangerous. (Speaking from experience!)

The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
