Replying to broken binding/brakes

I broke my binding (rossignol freebinding like the look barrel ones) tonight when i ejected from one foot doing a 540, i got up and wasnt hurt at all but i went to put my binding back on and my brakes wouldnt go all the way back up and were dragging on the ground. after further inspection the part under the thing that pushes the brakes up was broken and i couldnt fix it without doing anything that the dealer wouldnt like me to do.

any suggestions that you have are appreciated (does a warranty cover it?)
