I used a laser thermometer to adjust the brakes on my 37 Ford. Cable operated mechanical brakes at all 4 wheels. Read the temp of the drums and tighten-loosen to get them as close to the same as possible.
Once grabbed a rotor on a Z car with a stuck caliper. I had deep callouses on my hands and before I realised how hot the rotor was it had branded.
"MIN DIA 10.5 MM"
on my callouse (SP?) at the base of my fingers right where the hand begins. You can touch the rotors quickly to see if there is a significant temp difference.
