Review: Drum brakes. - Truly Amazing! truly saved from a fine with my semi-truck brake adjustment. bcuz i can measure the clearance between the drum & the pads.
Review: Acceptable quality, easy to read markings and nice long reach. - This gauge was acceptable quality, engravings were easy to read and the long reach was just what I needed to check the gap on electric motor brakes on a warehouse crane system. The only issue I had was with the nut and bolt, the nut was a nice design and easy to tighten without a tool but at the same time it would come loose and fall out. I had to constantly tighten to prevent it from falling out. After a couple days of this, I replaced the thumb nut with a nylon nut. I didn't consider this enough of an issue to reduce the star rating.

### ⭐⭐⭐⭐⭐ Must have for deeper gap measurements
*by D***L on January 2, 2026*

These extended length feeler gauges help me to perform my job even better, allowing me to reach where the normal short feelers will not reach. Metal construction is great and functionality is great, only gripe is having the skinniest size on the outside causes it to crease and eventually it tore off, I should have moved them inside a little to prevent but didn't think about that till it tore off.
