Turns out, Dexter tells me this morning these are not self adjusting brakes. Once adjusted properly, they can become under adjusted on their own (of course, due to wear), but they can't become over adjusted on their own. Escape mfg. says they were adjusted and owner is to readjust at 300 miles (which would be before it even reached home from the original purchase). Obviously, they were not originally properly adjusted. Beware of the Escape warranty and customer service. It's an expensive RV unit with no support from the manufacturer. They accept responsibility for just about nothing! BTW, I have been involved in RVing for decades and am very familiar with electric brakes and drums. IMHO, there is seldom a need for disk brakes in place of drums. Next trip, coming up soon, will tell the story.
