front wheel noise .

hi im looking for a little help or any ideas , there was like a scraping or summat catching noise on my uncles bike when the front wheel was spinning , so stripped calipers cleaned and new seals etc , wheel bearings seem fine , but noise is still there you cant hear it at speed but when slowing up to junction but soon as you just slightly touch the brakes the noise goes away , so any ideas , thanks .

 

My first thought would be brake pads lightly rubbing on the disks, this is quite common, especially as you suggest the noise dissapears when applying the front break.

Another possibility is a brake hose moving against of the retaining clips.

 

easy to miss the buttons on a brake service but they are very important. Just use a nut and bolt and a ratchet to wind each one round and round. Do not use any lubricant though.

 

will try that . thanks

 

I done this to my VTR
I did use a lube but only a tiny bit and cleaned all round afterward
some of them where seized

 

look on youtube and it will show you how to do it
bolt with two nuts on
tighten nuts on bobbings and turn bolt carefully

 

This is all new to me because I come from the 'drum brake' era

It seems you're saying the 'buttons' should be a tight fit but still able to rotate? (Hence the term 'floating discs' I guess)

And your means of checking is to run an appropriately sized bolt and nut through the holes and then tighten and rotate the whole button?

Edit just seen new post above re You Tube. Will check, cheers!!

 

what are they called
buttons or bobbing's
I call them bobbing`s

 

bobbings . me to ,

 

I do it a bit different
I use a bolt and two nuts (which can be nylock)
I put the bolt through with one nut already wound on and then nip the bobbin between the two nuts,
then I turn the bolt backwards and forwards

 

I had not even known that this was a thing you need to do! Thanks for this

 

Like nigel has said
That’s the reason it’s a floating disc
And you can buy new bobbin’s
