Could anyone tell me if this is a common occurrence w/ disk brakes? Is it even a thing? Will it be covered by warranty? I'd just like to know if I'm being told the truth.
I don't know if you're being told the truth, but it is possible for the pistons to get stuck. I haven't seen it happen, even once, on a bicycle, so I would suggest that it's not common. I, also, can't imagine it would happen on both the front, and rear, at the same time, unless there was a manufacturing defect which should be covered under the warranty, unless someone added the wrong brake fluid to the reservoir and gummed up the works.
