Approximate dimensions

The thickness is approximately 1.8 mm. Check the diameter on your specific vehicle, as the front and rear brakes of the same scooter may use different disks. Also, compare the mounting pattern on the hub.

Disk replacement and alignment

• Replace the disk if there are cracks, permanent deformation, or wear below the minimum thickness. If you hear rubbing, first check the caliper alignment.
• Clean the hub mounting surface and install the disk in the indicated rotation direction. Tighten the bolts gradually in a cross-pattern to the specified torque.
• Keep the braking surface clean and free of grease. After assembly, check for free rotation and braking; the new disk and pads require a proper bed-in period.
