Yes the caliper has a little play. Good discussion all. I appreciate it. I’m new to the forum but been on minis for 30 years. Finally have a dollar to play with them with my son. Working on a go kart as well. Clocked it at 49 mph so I’ll put some of that good stuff on the mini as well. This is fun. I’ll post an after pic of the mini bike when it’s done. Thanks!
