Free Floating Discs

[T 24]

Because the tension-washers on the back side wear thin when you spin the bobbins. If they are gone you certainly have a clunky disc.

You don't need to turn them tens of turns.

Exactly

Every now and then i stick a bolt thru, give them a turn with some cleaner. Doesnt concern me much. Never really noticed difference before and after.

I get a loud clicking noise from mine when the bobbins seize..I've just done them and loads of white corrosion dust came out.
All nice and quiet again now.

This is what I used.
M5x20mm bolt and nut, plus the dished washer. It grips beautifully. The dish formed itself when I tightened it all up prior to spinning it.

Hi

New GSX 1400 owner and first post here

I used this tactic and a washer cracked in half.

How screwed am I?

If it's just one washer I would say you will be okay to ride, disk might make a clicking noise in use but nothing to worry about.

For goodness sake folks, stop mucking about with your `bobbins`

Virtually all of us will have semi-floating rotors up front - i`m running EBC`s which are excellent - and they all will `click` noticeably, some of the time. Its totally normal and the product of the rotor movement against the bobbins as the pads bite. The bobbins themselves don`t need to spin, why would they ?? They certainly shouldn`t collect `crud` either due to the surrounding parts `moving` under load, ie. expanding & contracting etc. etc.

To replicate the `ticking` sound, just drop the wheel away from the calipers , grab the rotors and shove them sharply side-to-side and you`ll hear the noise as the rotor moves against them. Thats exactly as they should sound.

On the other hand, stick a bolt through them, attach it to a drill.......and wreck them!

Years ago on old forum, big talk about keeping bobbins clean, spinning etc.I did it a couple of times. Something you were supposed to do. Never noticed much difference, havent bothered for maybe 8 yrs. Still work fine.
