Temperature gun for brakes and bearings?

I also use one, check when we pull into rest stops, get gas, etc. Mainly looking for a variance from R-L, also check the toads brakes to make sure they're not dragging.

Like Rover Bill pointed out look for variances for spotting a problem. I have a a IR temperature gun for that purpose as well. Harbor freight has them for very little money. Fluke makes a higher quality unit.

I always use mine to check the brake drum and bearing temps at my first rest stop in the morning when driving. Any wheel with a higher than average bearing temp or a colder than average brake drum temp indicates a possible problem with that wheel.

Yes, simple, quick and effective, what more could you want? The only place I have used the temp gun (after I got over playing with a new toy) was to hit the inside tire on the DP duals that I can't reach unless I get down on the ground.

I have a Fluke IR temp gun I really like. But I rarely think to use it, so perhaps your post will remind me next time I'm towing.

I have a couple I bought at Harbor Freight. On long downgrades I will stop at a pull-out if I notice any signs of overheating. I use the gun to check for consistent brake temperatures. Then I wait to go on until they get under 100 Deg. Good time for lunch. Otherwise the best way to cool them off is a long run after I get down from the pass.

I used mine to read temps on springs in Yellowstone. Lots of people asked me how hot each spring was. And yes, I have checked brakes and disks, but more just to see if they all matched. Usually in a car or motor home, the smell is the first clue, but I can understand how important it could be for an airplane. Problem is that most american drivers have no idea about brake failure due to excessive heat. Just watch brake lights on other cars when going down a long interstate grade. Or trucks pulled off with smoking brakes on their trailer.
