Monitoring brake rotor wear is essential for consistent braking performance and rider safety. This tool is designed to measure brake rotor thickness and help you quickly and accurately determine when replacement is necessary.

Product attributes

To use it, simply slide the appropriate slot in the tool over the brake disc.

If the disc does not fit in the groove, it is still within the safe wear range

If the disc fits into the groove, it has reached or exceeded the minimum thickness and must be replaced to maintain braking performance and safety.

6 precision laser-cut measuring grooves for wear limits: 1.5mm, 1.55mm, 1.7mm, 1.8mm, 2.0mm and 2.3mm - each groove is marked with the minimum thickness specification used by the most popular brake disc manufacturers.
