I think another factor in using the grease zerk (EZ Lube) feature is the temperature of the grease and bearings. If you are doing this on a cold spring day in cold weather to get ready to go on the first trip of the year, the grease is much thicker and harder to work thru the bearings and possibly more likely to push out the axle seal and get into your brakes. Might be better to do it in the middle of the summer on a 90 degree day. Also, make sure the trailer wheel is off the ground and rotating while you do it.
Me, I just do it manually by hand every 2 years or 10k miles. I have had one failure, not sure what caused it but the axle was likely over loaded as well. That is why my 8k lb trailer now has 5200 lb axles instead of 3500 lb axles. The bearings on the bigger axles are HUGE compared to the original bearings. I also monitor my bearings with an infrared heat gun to make sure they are staying cool. No issue the last few years with the bigger axles. Before I just check by hand so it is hard to say. It was also super hot the few days before I had my issue and I was in Arizona near the NM line when I saw smoke from the trailer. Fire extinguisher came in handy!
There are a lot of variables to consider to keep your bearings and brakes happy. Good luck.
