Floating vs non-floation rotors pro/cons?? - Ducati.ms

Almost ready to do it but not sure of the real value. My 95 900 SS/SP had them from the factory. Now they are I guess what they call them semi rigid. Definitely not the rattle float of the 95. So is there anything to be gained. Brakes seem pretty awesome on this 999S with out the float.

You won't notice much difference unless you are tracking the bike to be honest.

They are not a huge difference- but there is a difference.

The full floaters tend to spin a little easier as they find space between the pads so you end up with less rolling resisitance. I notice it when I'm pushing the bike around.

Pads generate less heat and heat transfer to the brake fluid as you are riding because they are not always rubbing on the rotors. This can reduce brake fade.

Full floater buttons are usually aluminum, so they are usually 1/2 lb lighter overall. Not a huge difference in itself, but if you are trying to build a lightweight bike - every little bit helps.

Great points. I found in a thread that they can cause premature wear in the carrier contact area, but that could be 50K since no real mileage or type of ridding was given. Any one experience this?

I installed a set of Brembo HP rotors on my 999 (thank you MotoWheels!). I had axial calipers at the time, but it did make a difference in braking, feel. IIRC the OEM rotors are semi ??...the only downside, if you can call it that is they do make a disturbing clicking-creaking noise when your pushing your bike around....

i love mine and the sound they make although these newer stainless ones from brembo aren't as noisey as the old cast iron.
the brake tech stuff is nice too in carbon, iron or stainless

Floation?

sound? noise? what??? who cares?? rotors are not suppose to sound cool, get whatever rotors produce the best results (aka braking power)...and/or last longer.

for best results replace discs with every pad change, so if you want best braking don't worry about the life of the disc. best and lightest discs on the market are the carbon discs, super light and lots of friction, work well on the road but they're not cheap. $1100 each last time i checked.
