Redcat MPX70
 

Hello and thank you advance for taking the time to read this.
I have been led to believe that the current kids atv I have, Redcat MPX70, is actually made/sold by Kazuma.

So my questions are based upon this information. If this information is not accurate, please do advise and I still would ask the same questions below

1. Kazuma web site for looking up parts
2. For over a year I have been trying to find rear brake shoes and rear brake hub. I am providing a link to pictures and wondering if anyone know where I can locate the shoes and hub (https://photos.app.goo.gl/zXwzTWXf5tthcD146)

Thank
