Approximate dimensions

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

Replacing and aligning the disc

• Replace the disc if there are cracks, permanent deformation, or if it is worn below the allowed thickness. If there is rubbing, check the caliper alignment first.
• Clean the hub mounting surface and install the disc in the marked direction of rotation. Tighten the screws gradually in a cross pattern to the specified torque.
• Keep the braking surface clean and free of grease. After assembly, check for clearance and braking; a new disc and pads require proper break-in.
