I take it your brake controller was just fine.
I too have replaced and adjusted brakes on many pre disk brake vehicles. Prior to disk brakes becoming prevalent, almost all drum brakes on vehicles were self adjusting and actually worked very well. Non-self adjusting drum brakes disappeared on American made vehicles in the mid 1960s. So todays RVs with non self adusting drum brakes can be considered “vintage” technology.
On a previous thread regarding dealer PDIs vs the PDI performed by GD, a dealer service rep replied that they “checked the brakes” and that it was a PA state inspection requirement. Pulling the breakaway switch is clearly not a proper verification of brake operation.
I started this thread hoping that folks would get their dealer to properly adjust their brakes prior to initial delivery.

They are but as you probably know those adjusters are only meant for incremental movement to take up slack as the shoes wear. I did a LOT of adjusting before I felt the shoes on the drums. RE PA state inspection that would only be done before delivery if I bought the trailer and registered it in my state, I bought it in Delaware. In the days of drum brakes on motor vehicles inspection was required bi-annually. It used to be they needed to pull two drums on opposite sides to measure shoe thickness. Adjusting the drums was a courtesy done by the repair shops. My inspection reports now show results for shoe measurement on two wheels.

I had new axles/brakes installed in the fall. The old brakes worked well at 7-7.5 gain after I ran separate separate 14ga wire for the curb side, highly recommended. Well I hooked up to the trailer with these brand new axles and brakes and gain was still set at 7.5. No brakes! Adjusted to 10, like very little if anything, I could idle and not be stopped. Adjusted them myself and hit the highway. Went about 70 miles, still felt weak so I tightened them more at a rest stop. Went another 70 miles and touched the brakes, burned my fingers. They worked at this point, but were super hot. I backed them off and they are fine now.
Lesson learned, it does take a couple hundred miles for them to seat, most of the time this is done during delivery for new units. If you replace them expect to have very little braking until they seat.
