Just noticed an optical effect that you can put to good use when evaluating the conditon of your brake rotors.

In this picture the reflection of the yellow tape measure shows where the rotor is not worn evenly because the reflection of the straight edge of the tape is showing a major dip, which of course the tape does not have.

Therefore the surface of the rotor changes from perfectly level at this point, probably in this case because the brake pads are not wearing evenly all the way
to the edge of the rotor.

Interesting!
