I guess I never considered that. I do not own a tool to measure caliper thickness. Can I just use any sort of digital caliper or is there a special tool specific for measuring brake disk wear?

I am driving the car today. When I get home I can immediately use my IR temp gun and see if that brake disk is hotter than the other. Although it might also be warmer if the bearing is bad too. Might be interesting to notate anyway.

Thanks guys.
