Thank you everyone for your feedback. I must say that I purchased my truck and trailer brand new at the same time, my truck is approaching 35k miles and I am just now noticing the overheating cracks on my brakes after frequently towing in all sorts of terrain, and I still have some pad life remaining on my brakes. There is a lot of good advice here and I probably should look into getting disk brakes for the trailer. I am satisfied with my towing capacity and payload; have had many discussions on that. But getting heavy duty brake pads for the truck and taking a good look at replacing the trailer brakes seems prudent. My trailer stops very well when I apply the brakes, it's just that I have done a lot of mountain camping or gone over lots of mountain passes where I ride my brakes, especially coming down the mountain, and I think that is where most of the overheating occurs because I often smell it when I am riding my brakes. The brake controller in my truck has an adjustable gain for the trailer brakes and maybe I need to increase that gain, although I don’t want to make it too tight. Again, thanks for the feedback.
