They isolate heat generated in the brake ring from the hub and wheel bearings, which is why they were originally developed (for racing). That isn't something that bothers us road riders quite so much, but they also minimise the risk of warping and over-heating. On the few bikes that I've fitted them to, replacing solid discs, they seem to improve performance, although I didn't compare them with a new solid one! I have three new floating rotors for my Glide, as I do my brake upgrade.

 

Link?

 

Go to the H-D website, then the Store tab. You can search for stuff for your bike, enter year etc and bingo!

 

Thanks Yep. Those are the ones I've got about 100,000 miles on. Still good.

 

Thanks for the feedback. So the floating rotors will work with the existing calipers?

Yes, direct replacement. I am now using them with the 2000-2006 calipers and adapters.

 

I wonder if they were OEM or aftermarket rotors? Any HD part number on the one that broke? I've never heard of it happening to a OEM rotor. Although a friend of mine had it happen to him on a top fuel drag bike at like 140 MPH or 160 or something. Those were not OEM.

 

I have floating front and rear. Self centering should stop better and less heat on disc, less warpage Don't do chrome, too slick.

 

Thanks Beemervet.

The current rotor is a SunStar 44136-84A which is a stock part #.


Thanks aces I appreciate the tip on staying away from chrome.

 

I just replaced a rear rotor on my RKC. The FSM says you can reuse the bolts up to 3 times before they have to be replaced. (I think it was 3). Anyway, I got the bolts out quick and easy with an impact wrench and reused them.
