Birzman Rotor Wear Indicator

The Birzman Rotor Wear Indicator reliably measures disc rotor wear, so you can check whether your rotor is worn beyond the recommended minimum thickness. All you need to do is try to insert your rotor into the tool and get a new disc rotor, if need be. This guarantees high safety and optimal performance of your disc brake.

Since the recommended minimum thickness of a brake system varies between different manufacturers, the gauge comes with four laser-cut slots from 1.5 to 2 mm, in accordance with the most common standards. You can find the most common brands with the right measurements on both sides of the tool to make it easy to read from any position.
