You would be better of if they were all missing! Blindly pumping grease into a hub is OK for boat trailers that go in the water, however you are much better off to just repacking the bearings every two or three years. While doing that you can check the brakes.

Absolutely!!!
I made ours inaccessible by putting hub caps on with no hole for a grease gun. 12,000 miles, 12 months is the Dexter recommendation for disassembly, inspection, cleaning and repacking. That's a bit too conservative for me so I use 12,000 miles or 24 months though historically we do over 12K miles a year so ............
