Re: Loose Rear Wheel Brake Disk
It is a floating disk, so should have some side to side play, but NEVER much rotational play. I assume you have 1/8" movement at the outside perimeter of the disk, not at the rivet pins. That is still too much. That much play can cause pretty severe shearing forces on the pins which over time can cause real problems. The sharp hits can cause the riveted fit of the pins to loosen, and worst case shear off. If it was me I would replace it.
