Replying to Look Pivot Brake Spring

Sorry I don’t have any pictures but anyway;

I have an old pair of Pivot 14s that I want to sell to my homie for cheap.

One of the brakes is broken because the spring that engages the brakes popped out. I tried to get it to pop back in but it was a huge pain in the ass so I just said fuck it and rode them anyway.

I have no clue where I put that spring. So now I’m wondering what my best option here would be. Can I buy just the spring anywhere?
