Monitoring the wear of the brake disc is essential for consistent braking performance and rider safety. This tool is designed to measure the brake disc's thickness and help quickly and accurately assess when replacement is necessary.

• Simple to use: slide the appropriate slot of the tool over the brake disc.
• If the disc does not fit into the notch, it remains within the safe wear zone.
• If the disc fits into the notch, it has reached or exceeded the minimum thickness and needs to be replaced.
• 6 notches for laser measurement with precision for wear limits: 1.5mm, 1.55mm, 1.7mm, 1.8mm, 2.0mm, and 2.3mm.
• Each notch indicates the minimum thickness, according to the most popular brake disc manufacturers.
• QR code linking to a step-by-step video guide.
• Built-in hole for easy hanging or storage.

Minimum thickness specifications printed on the disc or advice from the manufacturer's technical documentation are used to confirm wear limits.
