Review on OTC 6596 Brake Pad Gauge by Sonny Nevers

If you can position the tool to measure it works great. Using it is relatively easy, but the vehicle may not give you access. In some cases I can take the measurement without removing the wheel, in others the wheel should come loose. However, the measurement is done with one hand. Nice to have the number and now using this device will be part of my tire changing routine. One thing, however, is that the sensor must be protected during storage. The first option is to use the small pouch that it comes in. The second option is to use an OTC 7312 lockpick tube (pictured) if you have one, or something similar.
