You could use your temp gun if you like, probably wouldn't hurt anything.

I think a dragging brake can be felt, heard when spinning the wheels or even rolling the car.

I 'fine tune' the brakes just by testing them. I don't want it to shuck or jive and I like both rears to lock at the same time and both fronts to drag and lock slightly after the rears and stop the same. I adjust till they do. But, maybe thats just me.
