How much grease for wheel bearings?
I have run into this problem more then once over the years with boat and camping trailers. Over greasing zerk fitting on wheels and pushing grease through the seals and getting grease into brakes. ...

If you have the EZ Lube hubs, the zerk is there to purge the bearings and hub of old grease and replace it with new grease. BUT. You must do it correctly. And that means using a hand pump and pumping the grease very slowly while continuously turning the wheel. The grease is ported behind the inner bearing, then flows thru that bearing as it is turning, thru the hub, thru the outer bearing, and out the front of the hub around the zerk. That pushes all the old grease out. When you see new grease coming out the front you know all the old grease has been replaced. If you pump too hard or don't turn the wheel the pressure may push grease past the seal.
A pump or two does nothing toward getting new grease to the outer bearing. It takes a lot of grease to do it correctly.
Google ezlube for videos and how-to information if that is what you have.
