Replying to Rosignol fks 140 brake durability

Right now I'm on two different squires , I destroyed a nose piece of one of them and went through a solid number of 5 brakes this season. I don't know how i do this but it haappens all the time. Now I'm thinking about getting the fks 140. Are the brakes on them durable? Will it be likely that i get them bent or broken too? Is there a way to change them, or is it really as impossible as everyone tells it is?

Thanks in advance.
