Trailer brakes

Believe that the trailer industry standardized all parts sizes years ago. There have been lots of complaints on line about weak brakes on Lippert axles so I checked out Dexter to see if I could improve the braking on my 5200 Lipperts. In a 12x2 Dexter offers 5200, 6000, and 7000 lb rated linings. On line they don't seem to indicate any difference in the magnet, but their support folks readily said that if I wanted more aggressive braking, I should just go straight to the 7000 lb product. I got the whole backing plate installed and went with the forward self adjusting product for just a few dollars more. Still getting them broken in but already have a little more brake than the 5200s. Trying to get to the point where I can get the controller off 10 and the trailer is still braking its share.
