Feeling foolish now. Wish I had paid attention to normal operating display on brake controller.
Would you think that it's just a matter of trailer break that stuck for a while? Weird that the noise went away when we got it back to 8.
Would the fact that the are stucked prevent us or made more difficult changing the number on break controller?
Also, display showed 3 while screeching, and stopped at 8. Wouldn't 8 apply more pressure on trailer breaks?
