Here we go, another EZ lube debate!
I am the owner of a 2011 Keystone Sprinter with EZ lube hubs. I have been using the zerk fitting for annual greasing using a manual gun for 5 years. I also perform annual manual brake adjustments. ...

It's a high likelihood that eventually the volume of grease pumped in to the zerk over several years will surpass the capacity of the bearing cavity, blowing out the rear seal.
Previous owner of my cargo trailer followed the "there's a grease fitting, so I will shoot grease in it every year" maintenance regime.
It blew out the rear seal:

This is it! When people see a zert they simply pump grease into it. Pretty easy to do the "right" thing. I personally know very little about the EZ lube set up. I do know how a bearing buddy works. The problem I have with both of these is that most (not all) folks out there know very little about how to properly use the fitting to avoid blowing out the seals. If you purchase a trailer from a second owner chances are that your brakes will look like those in the photos posted.
With brakes, I believe they need to be inspected and adjusted yearly. If you are going to do this, then pack the bearings while you are in there.
