Im pretty sure they are semi-floating.. but I have no idea what that is!!!
no problems with the noise.. just the fact that it shakes... no problems below 30mph, at anything higher it starts to shake, but the pulsing in the brake leaver is hardly noticable, and its only when I use 1 finger I can feel it do that... will probably know in a few weeks time anyway.. only another 500 miles to its major service
