Noisy rear disc brake

Does anyone else's rear disc brake a lot of noise when riding due to it moving/ floating around whilst riding? On my my te310 it make a lot of noise to the point mates ask me if that's normal. Does anyone know if it's normal? Is there a way to reduce the noise?

Yes, they are noisy. You can get size up four o rings to go between the spacers and disc to elinate the rattle.

It's normal...

Normally annoying
Mine is producing more noise than it used to (Now has 4500km). If the disc is rotated and re-mounted it would tighten the tolerances close to "as new".. and it may be a bit quieter, for a while..
It will always rattle, just how it is designed.
I'd like to note that both the disc and pads are in excellent condition considering the distance covered on my bike.

Ha, I was going to ask the same thing. My txc is really noisy too glad to know its normal.

clankety-clank...mine does the same, I might try rotating it, honestly though, it doesn't bother me anymore

If I can still hear mine jangling I know I haven't fallen off yet.

They are suppose to "float" if it's high pitch you can use motorex copper paste, works wonders.

I like the sound of the floating rotor and chirping exhaust. Make for lovely sound to sing to.

Let's not forget the operatic qualities of the front brake.

?

Maybe his front brake squeaks?

Both of mine howl when they get hot. Guess it's normal ?

got my first husqvarna (TC450) a week ago the first thing i did was TIG welding the rear disk to the washer that holds the disk to the hub...

Braking sells a soild mount if you cant take it any longer.
Ive seen one of these derail when hit on a stump. What a mess they make when or if it happens.

Why not just use a little Silicon on it when mounting if it bothers you? Doable no?

Exactly what I was thinking...

Both my 610 and 310 have rather noisy front brakes once you warm them up. Never had a problem with the rear at all. I bought the TE610e used, but the TE310 has had the problem since day 1.

I did this by force squeezing some black hi-temp silicone into the gaps of the disc mounting areas. it lasted for 1-2 rides and then wore out and the rattling started again.
