Bought a Sunset Trail 33BD in April and love it. All of the manuals are in the trailer in a storage facility so I can't research myself right now. Do the brakes need to be adjusted manually or are they auto adjusted as they wear? If manual, how often should they be adjusted?
In my experience, pulsing usually indicates some surface rust on the drum or armature where the magnet rides.Â* Rust changes the coeficient of friction so you get more, then less braking.
Use it enough and the rust should disappear.
After how much use? I put 427 miles on it on our first outing. The pulsing seems to happen from about 15-20 mph to complete stop.
It was a rainy few days at Algonquin Prov park...tarps kept us dry.

Mine pulsed too and someone told me the trailer brakes were braking too much more than the truck. So, I backed off on the setting and the pulsing stopped. I still have plenty of braking power on the camper as witnessed by a couple emergency stops lately.
