Floating Rear Rotor?

Anyone know the why of Husqvarnas use of a floating rear rotor?

Any reason to not use a fixed one?

The floating disc is to assist the brakes in wet greasy conditions where mud etc. may attatch to the discs/pads and cause premature wear. The floating aspects adjusts better to lumps of goop. Only downside is they can at times rattle when at idle.

Or at the back of the van when your driving…..at lest until you sand the wife to the back to put a rug on it

Ok, good. I've swapped out the woodys cush hub off of my KTM to the husky and it's has a hard mount rotor. I figured to keep the nice wheel rather than sell it with the KTM for not much price gain. All it took was a bearing swap to match the husky axle and turn a couple of spacers......

Another benefit is a cooler running rotor and pads. Never to boil your fluid and have brake fade. But not a must .

Thanks for pointing me to this thread. I think I am going to run a fixed since I have it, unsure which wheel I will run it on. The 18" dirt wheel or 17" street wheel? Thoughts?

I think you would be using the rear brake a whole lot less when riding on the street, so I'd mount the floater up to the 18" dirt wheel and the fixed to the 17" street wheel.

It's not the rattle of the floating disc that gets me... it's the spark arrestor insert. Sounds like there're marbles in there.

That was my thinking also. I won't be pitching the rear like a good ride could.

I guess I can see that logic also.

Time to make a caliper adapter for my 320mm front over the winter and I am set up! Thanks

I was riding around in on the "lawn" today just practicing slow speed maneuvers and such. I kept hearing this crazy rattling sound. It didn't take long to figure out it was the floating rear rotor. Today was the first time I ever heard it, and I was wondering if it was normal. Thanks to those who have posted about it rattling here. Saved me some worry.

(I suppose I've never heard it before, b/c I 've previously always had the spark arrester in place... the rattle of which nearly drowns out the motor.)

I was told the SA rattles to keep it from being stuck by the carbon deposits that settle on it....so I didn't even try and "fix" it. It's a "feature"....

Strange, I too was putting around in my yard today and noticed it rattling around for the first time.....

I took the sparky out and applied some hi-temp silicone to the thick round (solid) metal part that fits tight to the walls of the opening. Reinstalled it and the clip ring. Wiped off the goober and let it dry overnight. No more sparky rattle but the disk drives me nuts.

If it's REALLY bad I'll touch the brake. PADS ARE CHEAP

I agree. What the hell are you all focusing on out there on the trails? I have never once noticed anything but what's in front of me. Thanks, I'll probably notice it now and it will bother me.

Hmmm. That's probably true. Whether they intended it or not!

Ha, well I will say it VERY RARELY bothers me. I only hear it at slow speed on pavement and well usually if I'm going slow I'm braking really hard

I only hear it pushing my bike or idling or now riding behind my old bike!
