Binding Disc broken
So I have a crack in the disc in my binding and it caused it to turn and change the angles of my bindings when I'm riding. I figured it happened because my screws were too loose and it caused them to wiggle and crack the plastic disc. I have heard they are under warranty from Burton if I bought the bindings from them. Should I get a new disc or just keep my screws tightened and not worry about it?
