Replying to Problems wih Marker 11.0 Free?

I've been having a sh*t load of problems with my Marker 11.0 Free's, like its popping me out when I land my jumps, or when it receives a big impact. The part that connects the brake to the rear part has also snapped TWICE on me, both in less than 4 days, both on the same binding. I broke it landing switch on  180 on a small step-up. I brought it bak to the shop, but they told me no warranties on brakes so I paid the $45 then it broke on me again 2 days later, same binding. Both same prob.

Is this just my bindings, or is it a popular prob. and should I spend $ to get them fixed again or should I just chuck em and not jip $ on bindings nxt time?
