I have a National 2000 seaview 31 ft.and at a recent inspection was told I should thinks about new brakes rotors and pads. The vehicle weighs 17000lbs and I have towed a dinghy (2800lbs) about a third...
New to forum, but I just retired from working on heavy equipment for 36 years. I didn't replace a drum or a rotor unless it was out of spec. or broken. Shoes and pads will burn in but you must be wary the first several stops. Same as first driving a RV that has sat all winter, you must burn the rust off the brakes to get full stopping power.
