How about using a flashlight and mirror and inspecting for the depth of the wear indicator? If you can't see the slot in the pad you better be changing them really soon before you wear them down too thin and your puck comes out. Makes a real mess and is not fun to clean up, and then it requires servicing and bleeding your brakes.
A preflight inspection of your brake pads will prevent a lot of headaches. If you're looking for an exact measurement, good luck with that!

If your pads are the originals included with the Cleveland brakes then they may not have a wear indicator.

If your pads are the originals included with the Cleveland brakes then they may not have a wear indicator. Mine didn't. I found this out the hard way. When you buy replacement pads be sure to get ones that have wear indicators. For example, the RAPCO replacements have a notch in the edge that you can see during visual inspection of the brake. Once the notch is gone you should replace the pads. I got the RAPCO pads from Aircraft Spruce. At the time, (late 2006) their price was substantially under Van's if you bought enough pads for a couple of changes.
