New trailer brakes

New trailer brakes. How hot and how much burning off of paint are consider normal?
  • This is why I carry and use a Infrared thermometer. At every stop I shoot the hub temps, and I shoot the brake drum temps on each wheel of the RV. I will provide invaluable data regarding bearings and temps.

    I even took off the decorative "cones" that cover the hubs to allow a better read on hub temps.

    Controller could have been set too high. The shoes and drums will have a certain run in time, too. I would suggest to check the hubs and bearings after a short break in time. I've read posts on here about loose bearings on new trailers. It's an easy thing to check if you can get under the rig with a jack and as long as you have a wheel up, adjusting the brakes is just another five minutes/wheel.

  • Well, one good thing is that you know the shoes are making contact with the drum. If they get too hot, maybe back off on the controller.
  • Breakaway switch is intact.
    Smell got better by the end of our short trip from dealership.
    All cooled down overnight. Shirt trip to campground today. Will see if it reproduces.
  • There should be no burning paint smell. You don't have the break-away plunger pulled, do you?
