Hi All,

The new 10 (or 11) Ultra is just around the corner and I always thought about putting on floating brake disks... although never got around to it on the Road King. What I do have on the Road King is pulsating front brakes. I've read this can be eliminated by the floaters, but also hear the floaters can make noise. Does anyone have HD floating discs and do you like them... pros and cons? Thanks

Dave

 

I have them on front and back and never had a problem with them. No noise.

 

Same here... 5000+ miles on mine and no problems... 04' RKC

 

Stock front rotor also warped on my 08 FB. Have floating now. No problems w noise. ...and looks much better.

 

Pulsating comes from a warped rotor. The floaters dissipate heat better so less chance of a warp.

 

This is why I come here... so many with so many answers the rest of us need from time to time. Thanks Dudes. Dave

 

Actually floaters allow for radial expansion due to heat and this lessens the chance of warping because of this. I have them on the front and like them but never had the stock front rotors on my 08 FLHX so I don't have a frame of reference for this bike.

 

my 07 street glide did the same thing, made noise and then started pulsating, put hd floats on and never had a problem since

 

Floating rotors will warp as well. The floating arrangement is to align the rotor with the centreline of the caliper/pads - radial expansion is not the issue, it's differential expansion due to material specs and manufacture that result in warpage. I've got floaters on the SG and they pulse already when coming to a halt......

 

The '08 Wide Glide came stock with a floating front rotor.

A caliper piston stuck on mine, badly warping the rotor - caliper and rotor replaced under warranty.

The new rotor warped about 15K later and was replaced under factory warranty.

Now at a little over 90K and the rotor is starting to warp again, but not bad enough to be replaced under the extended warranty according to HD.

So, floating rotors are not exempt from warping.
