DaveP - Where do you have them relined?
Blood_of_Tyrants - It looks like this brake was used to stop it at one time, or just forgotten to and left on for a while. They look baked. I have tightened it all the way and it holds on a flat. On an incline, it won't hold the 36k lbs. The outer shoe is contacting, but the inner one is not and I can't adjust it more.
