Just going by what he said, I didn't actually see it afterward. As far as the brakes, I only began to read them because of the 196 degree brake I saw through the wheel when scanning. It was "redder" on the imager than the rest and that is what got my attention. Again, my initial reading was looking at the hubs only but I could not ignore what I saw through the imager considering right after braking one brake only was 40 degrees hotter than the other three. Only after that did I begin to look at the brakes to makes sure my loosening the adjuster made a difference. Eventually it did after several small adjustments. It was the same noticing the brake that failed. I should have seen "red" using the imager on the perimeter of the drum after coming to a stop. It looked as cool as a pop cicle so that too got my attention.
After this experience, I'm gunshy or even paranoid now. Not that it was a life threatening experience or that the trailer exploded or anything like that but now I feel like I have to have something that will give me an idea of what is going on with the wheel hubs/brakes. I even shot the temp of the differential just to get an idea of what was going on with it. I shot everything that generated heat including the radiator, condensor actually as that is what is up front.
It's really a fun/neat tool to have along but as jmtandem stated it is more than one practically needs. It is really pricy and if I would have had to buy it, it wouldn’t have come along. I’m glad it was available. If ever I had to buy one, it would probably be one of those Harbor Freight ones that was mentioned.
