The drum brake adjustment gauge is a measuring aid that allows you to adjust the gap between the drum brake shoes without relying on the sense.

■ Traditionally adjusting the drum brake has been relied on the sound and feel of the drum when turning the drum, but this product allows you to adjust the gap between the drum and the shoe using a thinness gauge, etc.
■ For example, if the inner diameter of the drum is very different from the left and right side, you can adjust it to the same gap.
