Replying to How to fix/replace brakes on Pivots

How do you fix/replace the brake on a Look pivot. I have an arm that is broken on the one side of the brake....

I know it is tough to do this but, there has to me some way. The only way I can think of right now without pulling the binding from the ski, is to get another brake and cut the one side off and weld it to the pivot broken piece....the spring is also fucked in there but this would mostly solve the problem...i hope you understand what i am talking about...
