Frequently asked questions

Here you will find answers to frequently asked questions about this repair.

What do I do if the motor mounting cannot be loosened?

Always work with the right tools and without Force. If the nut or a bolt cannot be loosened, we recommend that you do not force the repair.

Yes, after fitting the new brake disc you should definitely readjust the brake and check its function carefully.

Can I continue riding with a dragging brake disk?

No, if the brake disc grinds after the repair or the braking effect is unusual, you should check the setting again or have the VMAX e-scooter checked by a service center.
