Getting very annoying now!

Changes with wheel speed (gets faster / slower).  Noise changes slightly under very light braking and goes away fully under normal braking.  Seems to also go quiet when I steer left?  Then always comes back again.  Not noticeable from cold, but after a few miles is present down to 10/15 mph.  On way home tonight it wasn't there until I applied brakes on m.way then it was there all the way back! 

Back in the garage for this tomorrow.... again

What am I looking at?  Sticky caliper?  Warped disc?  Dodgy hub/bearing?  Help!

[spetzdude]

have you recently changed the pads or disks?

the pads could not be aligned properly?
worn out pads?

Had the same noise before, changed the discs, but its come back again. 

Noise is intermittent so it must be related to wheel rotation and the brakes rubbing.
The pad would be a constant noise no?

Only came on again tonight after a few miles and after applying the brakes.

Pad stuck out rubbing on disc (possibly warped again) due to sticky caliper? 

[topher]

have you jacked the front up and given the wheel a shake to check the bearing?

[spetzdude]

"The pad would be a constant noise no?"

No becasue it would be rubbing on the disk.

best thing to do is what topher said and wile your doing that have a good look around and spin the wheel, if you still cant see anything, take it to a garage where they have ramps, so they can have a good look.

Is the dust shield bent and touching the disc. That could be one option.

[Mr_Orange]

Sorry dude I know what you are saying.  I meant to say if it were a pad issue (worn, glazed etc) it'd give a constant contact noise on disc under braking etc, which I aint got.  I'm thinking slight disc runout / caliper stuck out, as it chirps slightly with each rotation of the wheel.  

Bearing seemed OK when I looked, no play there.  Manually spinning that wheel there was a slight tight spot.

I've also checked temp of wheel and caliper after a good run and no different to other brakes.

I don't want the garage guessing with my money what the problem is, and to go there armed with some idea what to expect.

Good call.  I'll have a look!

I had a noise coming from my N/S/F wheel, it was more a knocking, metal noise, when i went over rough ground i could hear it rattle, sounded like one of the springs was loose.
When i touched the brakes i could hear a clicking noise   
Anyway i took the wheel of looked at the ARB bushes they're a little worn, but not major worn.
I took the calliper off and the rear pad anti rattle clip was loose and was moving around in the calliper, bent the clips out a little for a tighter fit and the noise has gone.


Good luck Mr Orange.

Help!

Hi
If there is a dust shield at the front behind the disc, then check that it is not catching anywhere.
