Thanks so much for the reply.
Completely agree you way too much over hung load for any serious off roading.
I have come across the info on KinRoad karts found some parts list info but no luck on finding anyone who carries the caliper they show for use on their karts that look like mine.
It appears the caliper they use is an integrated lever actuated hydraulic caliper.
But in other videos and photos I get partial views of a much smaller mechanical caliper.
I'll post pics I have found.
I'll also include a link to a "working" website that has all the parts list for the KinRoad Karts.

I my search you sure hit a lot of dead websites....
Well again thanks for the reply and another lead.
