I am going to start documenting all my brake temps with the infrared gun now that everything is new there.
Previously I would judge temps by feeling the heat with my hand on the rims.
Where would be the exact correct place on the rims or drums to get the most correct temp values?
And roughly, what should those values be? It is a stock brake system with 80mm calipers up front.
Thanks, Scott

The problem with checking brake temps is they will vary widely unless you coast to a stop just prior to checking them.
When I stop at a rest area after running a while on a an interstate highway, I usually coast in to the rest area and try not to use the brakes. Then I walk around and check the the temps. If one is considerably warmer than the others then that brake is dragging or something is else wrong. If I want to check the actual brakes after use then I use the brakes when coming in and check them for differences between each other.
The brakes and tires will always be warmer on the side that has been running in the sun.
I am usually more interested in tire temperatures than brake or hubs temps. So I also check them at the same time for differences. If one is considerably warmer than the others, then I go look at the tire pressures.
