On post #50, look at the brakes. I have the 10 inch size brakes, but also, my brakes are self adjusting when putting on the brakes going Forward.......
I had no clue of these self adjusting (braking forward) being on my unit. Not a bad feature if you know that you have them and check and adjust them when needed. Since I had this unit I have taken trips to the Rocky Mountains and the Great Smokey Mountains. Do you think that I had to use my trailer brakes, a laaawwwt? Duh, you bet shaa I had to. If you have these self adjusting brakes, check them now
for tightness..... It may save you from having to replace an axle/bearings/brakes..... and a day of break down while on the road.
