Hi last time some good advice here helped us fix the NOMA electric lawn mower. But since a while now the right big back wheel simply bends away. The adjustable steel braked simply has gone soft like butter. I can't find any online residence for that brand anymore. So I chasing luck maybe someone has an old one in Vancouver? Or just some wheels like that WITH the bracket. I have been looking on Freecycle and in 2nd hand shops but no luck and don't know otherwise how to fix the "soft" wheel. Thanks a lot.
