A couple of peeps have indicated the button design on the discs is a bit poo, and in reality unless is it sterile clean they really don't float that much contributing to the warping issues. So if that isn't rectified ( and other issues like sticky pistons) it's only going to happen again. Mine squeal like piggies all the time and my braking pulses at higher speeds (though I'm not sure it may be suspension chatter). It's getting to the point I think the change of braking efficiency is causing the ABS to occasionally have a wobble. As I've said I've put in a order for some fully floating jobbies, - they better be good!
