Free Floating Rotors

Has there been a thread on this yet?
I'm looking for info because the front rotors on one of my track bikes are loose. They were that way when I bought it. I was told it was intentional and I did read something about 9 months ago, but it was brief and didn't really give much information about it other than it takes just a pinch of friction off the pads when you corner hard and the bike flexes. Solid rotors come in contact with the pads, but free floating will move out of the way.

The area where they are loose is the small rings that actuall transfer braking load from the rotor to the hub.

Are these rotors really "free floating" or just plane old loose?
How do I tell?
If they're just loose can I bang the out of them on an anvil and tighten them back up?

or what?

I sent mine back to Galfer and paid 200 for new buttons.

They rattle a little on rougher areas of the road.

braketech's are the only ones that are, imo, TRULY full floating. imo, this means there's no braking force transferred through/to the buttons. only rotor to carrier. but i know that others ARE technically full floaters. but i don't like knowing a little replaceable button is in charge of transferring all that stopping force from the rotor to the carrier. it's really more of a carrier/rotor design that makes them superior. but the availability leaves you wanting/waiting.

Got any pics?
Are they stock rotors someone has modified or aftermarket rotors?
Almost every brand of floating/semi floating brake rotor, including OEM, use buttons to attach to rotor to the carrier.
The thing you want to check is that the buttons or the carrier haven't worn, allowing radial movement or play.
If you bring them by I can look at them.

absolutely... i was just saying i don't like knowing the buttons are used for any force transfer. i prefer them to be there ONLY to hold the rotor to the carrier.

i.e. - braketech. (see how the stopping force is transferred directly to the carrier, and not THROUGH the button... that's all i was saying)

I'll get some pix. I like the config of those Braketech rotors also. Hmmmm.....
Mine look like OEM and I never really looked "close", but they do have radial movement. It doesn't look like there is any way they can fall apart though. I'll see if I can get some close-ups and post them. I'm way down in Webster so it might be a while before I could get them up to Motorcycles Unlimited.

while standing beside the wheel, you should not have any looseness that allows you to "spin" the outer part of the rotor. it is okay if you have a little side-to-side (push/pull) movement in the buttons. This is what makes floating rotors and semi-floating rotors different. The idea is that the friction ring is able to expand and contract without binding on the buttons, which allows the brakes to have almost zero friction drag when not applied.

^^^^^ Agree. After these posts I think mine are just wore to , but I'll still check. They can "jiggle"??? in all directions. I'm guessing about .015 inch and one side actually seems more loose than the other.

These are beyond unsafe.. see the play from the button area being worn down?
