OTC 6596 Brake Pad Gauge

When you can get the tool into position to make a measurement, it works great. Using it is relatively simple, but the vehicle might not cooperate in giving you access. In some cases, I can make the measurement without removing the wheel, in others the wheel must come off. Making the measurement is relatively easy, though, a single-hand operation. It’s nice to have a number and using this device will now be a part of my tire rotation routine.One thing, though, is that the gauge should be protected when stored. First option is to use the little pouch it comes in. Second option is to use the tube from an OTC 7312 seal pick (pictured) if you have one of those laying around, or something similar.

Works great👍

I love the idea of this tool, however it's design still needs a bit more perfecting.It really does make gauging brake pads quick and easy, but as others have state it does not work on all types of caliphers. The color coded indicator make it very easy to read the worn condition of the pads, however it's a little difficult to get the gauge 90 degrees perpendicular against the rotor so you can take a accurate reading of the pads as the gauge is tip is not square or round.The tool is made pretty much of aluminium so it hardly has any weight to it. This is a bad and good thing. It's light to carry around, but so light it feels like I can break it very easily.The other thing I wish it had was a clip on it so I can attach to my shirt pocket.The last thing is that this tool does not work on brake shoes.Overall, I'm happy with this tool. I use it whenever I can to check brakes at work.

We have used this tool for a few months now. Works good on most vehicles etc measure the brake pad thickness without removing the wheel.

Overall I will say this is worth the investment. I am an automotive tech and I will say this works pretty good most of the time. However some brake pads don’t have enough clearance to use and as others have stated if your pads are below 2mm it reads 2mm which is not a big deal because if my pads are 1mm and it’s reading 2mm either way they are in need of replacement.I’m not going to say this is the best thing since sliced bread but if you can use it, it is worth the investment

Saved plenty of time using this tool, helps me get accurate and quick measurements of brake pads, fits through most wheels.

Doesn't work on the vast majority of brakes. Caliper and caliper bracket are usually in the way.

Useful tool for easy and precise measurement of just how much of your disc brake pads are left without requiring removal of the wheels unless you are still running with steel wheels and hubcaps. Arrived quickly and even came in a heavy duty plastic pouch which you can use to store the gauge on you peg board when not in use. Highly recommended.

This gauge is perfect for measuring the inside brake pads without having to remove the wheel or if there is no inspection slot. It also is great if you can't get the normal measuring gauges in due to caliper design. It takes a few times of using it to get the hang of getting it in and getting a reading quickly but overall easy to use and a big time saver.

great tool easy to use and use it every day now

Easy to use,gives an accurate measurement instead of a guess

Makes checking brakes without taking the wheels off possible/reliable. Doesn't work on all brakes but most. Takes a lil getting use to but works great.

Does measure very well
