Make sure you have life insurance so your family is cared for.....
I had a recent issue with the rotor hitting the brake mount occasionally when I shifted weight to NDS. I assumed for some reason it hits the brake pads. but it turned out it hit the brake mount of the fork. I investigated the Shimano hub (100mm QR) and it seems the one one side spacer with the cone nut is wider. I swapped them so the wider one is on the NDS. that problem had existed a few years. i have no idea if my fix made it right, or if it came assembled wrongly from factory, or if I did it wrong when servicing the hub. I had built the wheel myself. that swap moved the rotor about 2mm inwards and resolved the occasional " ding". so i would check that. but with a knockoff fork, it also could be a weird fork issue.
Good luck. With a fork like that you will need it.
