If you have to execute adjustments on your own Kymco People then it is always recommended to possess a Workshop Manual to use as personal reference in case that you need to know proven methods to strip off a specific component like the Brake Pads and fit it again in the right way.
Kymco People Workshop Manuals will provide you with identifiable diagnostic guides with regards to your vehicle so if something is playing up it will help you understand what the problem is and ways to repair it. You will be able to assess if you can do this yourself or in case the job is just too big you can actually make a reservation for your People into a decent repair garage.
