Re: (ET) 12M brake disc

["RJ Kanary" <rjkanary nauticom net>]

   If the disc is loose on the aluminum hub, that issue must be 
addressed.If the aluminum hub slides freely in the brake stub shaft,and the 
disc is firmly attached to the hub, that is normal.In order for the brake to 
work effectively, the disc has to be able to 'float' along with the caliper.
