If your hydraulic disc brake is rubbing, please first ensure that this is not caused by a bent rotor. Put your scooter up on a chair so the wheels are spinning freely. put a light source behind the rotor so you can easily see if the rotor is bent or if it can be fixed by slightly aligning the brake pads.
Also check the rotor for play and tighten the mounting bolts if necessary.
The pads can be adjusted as follows:
6. Tighten the screws all the way (6-8 Nm force) to finish the job.
In case your rotor is bent and unless you have a severe wobble in the disc, we would actually recommend you try truing the rotor first to see if that will be sufficient. Any smaller wobbles can be easily removed. You can use a tool like this: https://www.youtube.com/watch?v=O0c2Ez2v0PU
Bike shops in your area should be able to help with that as well.
If you are not able to resolve it as per the above instructions, we can certainly provide a new rotor.
