Yes never use brass in that situation,but I am wondering did you intend to use the older race again?Never do that, timken bearings wear in, hard to duplicate that.I do use a hot plate to warm up a hub when installing new outer races though makes the job easier.

Put the races in your freezer, or even better dry ice.

Yes that is a even better,we use to order dry ice when replacing shafts on vacuum pump rotors.We kept the shaft in dry ice for 4hours before pressing on.When putting sleeves in gear boxes, I would put the sleeve in a freezer for an hour or so and they would just slide in,surprising how much they shrink the OD.

They make a race remover kit that is real handy. For years on the farm I used the big socket and the punch. Now I use the race remover, it fits right in there and bam there out. Harbor Freight has them.

I would weld a bead on the inside of the race , the heat pulls the race in and easily pops out with a heel bar, done alot of planetaries like that. Another way was heat the race rd hot turn it upside down and walk away 15 mins later you hear the race hit the floor after it fell out of the hub, either would work on a tiny trailer wheel hub wouldn't know why there are not slots or a bit of race exposed, get a bigger hammer (5lb mini sleadge) and a hard squared up punch
