Your better off using 50/50 solder as it flows better on brass, the "silverbrite or "silver solder" is junk, it'll soon fester with oxidation

and a brazing rod or "silver braze"(not to be confused with solder) is just too high a melting point,..... silver solder has a 450+ degree eutectic, where as 50/50 has a 360+ degree eutectic point
