Floating Discs

My Daytona has floating discs on the front and apparently they are supposed to have some movement and can also rattle.
I've never heard mine make any noise before or noticed much in the way of movement, but whilst putting the bike away I heard a noise and investigation found excessive movement in 3 of the pressed rivets.
Is it normal for these rivets to come apart?
Anything I can do besides buying new discs?

 

Get the rivets tightened up , there,s a place in Greenwich. I,ll find out their name.

 

Hi Dave, It looks like they have too much play, thats my gut feel. I would have assumed if they were meant to have that much play, all the rivet points would have similar movement, but those 3 look pretty loose

 

The Greenwich place is

Cheers Alan.

 

Here to help mate.

 

Is there play in the rotational direction; if not I wouldn't worry? My AP racing discs slap side to side but have zero play in the rotation.

 

I agree, so long at there's only lateral movement I don't think it's any prob. I'd have thought whatever play there is should be the same in all of them though.

 

Don't suppose it could be that those without excessive movement are being 'held' by the pads? Even though the brake is off.

 

Les, It just seems to be 2 extremely loose rivets. I have another pair of discs coming from a 675 owner and then I'll probably take the originals to the places suggested by Alan to get a price for re-riveting before selling one set.

 

Mine are all seized on one disc. Is there a way to release them?

 

Mine released when heavy braking from 3 figures whilst hitting those raised yellow stripes painted on the road!!

 

Yes mate , tighten a m8 or m10 nut and bolt onto each one, continue turning and bobbin will eventually turn.

 

Thanks mate! All i get from heavy braking is loads of vibration through the arms! And Hornet; we discussed this at work. I chickened out of the long screwdriver through the holes idea!

 

A bit of a scrub with brake cleaner and a stiff brush helps as well. Have a ride up to Northiam if no luck. Did you sell those bikes.???

 

No joy with the bikes. Still in my garage hoarding room!!

 

Will try to get down for a look soon. Can you pm yer number for a chat?
