I've used brass gears before in FRC, and I wouldn't ever use them again in torque carrying situations. They were way too soft and wore too easily when interfaced with steel gears - they needed to be replaced fairly often as they quickly turned to dust even when well greased.

There are some alloys of bronze that would be a lot better, but I suggest that you use two of the same material gears and lubricate them well. You do not need to use the gooey grease, there are some good lubricants that form a fine film like this one that won't attract carpet dust:
