Unbalanced (left-vs-right) RV Trailer Brakes
We have a 2014 Flagstaff Micro Lite Trailer which has only been used three times. Hitched to a new RAM truck with factory brake controller set with gain at +6.0, the left side brake drums get untouchably hot in stop-and-go traffic or on grades, whereas the right side drums remain near ambient temperature. [First trip was pulled with a Tacoma with the same overheating results - problem is not the truck]. Seems to me that the left side brakes are over-working compared to right side - possibly right brakes are not working at all? Dealer has repacked left wheel bearings which hasn't solved problem - didn't think it would anyway, since in light use the left drums do not overheat. They also adjusted the left-side brake shoes.
Any suggestions when I return the trailer to the dealer tomorrow for another attempt to correct this problem (which has occurred since the trailer was new)?
