Loud Clicking noise by tire? Brakes?

[amijab]

Hi everyone
I am new here. We purchased a used Trailmonor 3124kb and have aleady gone on 9 camping trips this summer! Loving it! On our last caming trips, as we were pulling out to go home, we noticed a loud clicking noise by the tires. It seems to happen more when we put on the brakes. We are supposed to go on another trip tomorrow but.... now I am getting worried. Has anyone every experienced this? It seems that maybe the brakes are grabbing when they are not supposed to or something. It does not seem to slow the trailor down.
Thanks for any help!!
