brass will be fine. Practice on scraps first if you are unsure.
I have spent days on end brazing caps to stays at Trek. Somebody had to do it. Back then, we only used nickel silver on everything that we didn't use silver on. I have always been curious why. Brass would be a lot better, some people develop a sensitivity to nickel silver. Nowadays I only use nickel silver when I'm working with stainless.
