I just decided to replace my old Hopkins proportional brake controller with the p3 after reading all the good reviews. I also want to be better informed on what's happening electrically with my brakes...
I can see where grease could be an issue. If I do indeed have to replace my seals and/or brake shoes, where would be a good place to order them from? I think mine are10x2.25. The axle tag says al-ko j40 4000 lbs.
