Should there be play in rear brake My rear wheel can move about an inch when the brake is completely locked. The movement is in the connection between the hub and the disk. As you can see in the picture below, the disk is held to the hub by 6 bolts and there seems to be another piece of connector metal between the screws. This connector piece with the screws seems to be moving with the wheel while the brake rotor does not. You can see a video of the wheel moving here https://streamable.com/g6k0ci. I'm wondering if this play is normal, or if the bolts are just not tight enough. The rotors are Shimano SM-RT66, 180mm, and it is on the 2021 Nukeproof scout 290 comp https://nukeproof.com/products/2021-scout-290. Thanks.
The video shows a broken hub. It should be impossible under all circumstances for the hub shell to move relative to the rotor. I can't tell from your pictures but I'm guessing that what's happening here is it's some kind of multi-piece shell as opposed to the shell being one piece, and the interface has failed.
