I just broke one yesterday.
I had it to tight where it connected to the binding and that with it being a few years old put to much torque on it.
It is good to replace every couple of years as the plastic compound they are made of breaks down over time and in extreme temps.
The plastic starts to lose the oil in it that gives it flex.
Keep a eye and replace your discs on your bindings if they are plastic or vinyl also as from experience landing off a huge tabletop and having one break into a few peices causes huge doctor bills.
Only ride metal now myself.
Keep a eye on the inserts on your board that you bolt your bindings into as they can start to pull out with abusive, fun riding style.
I just noticed I typed extreme, are you allowed to use that word here?
