Title: Strange sound when brakes applied
Post by: CVOTequila on November 02, 2009, 06:53:51 PM

I have noticed an odd sound when the brakes are applied, it sounds like something is contacting the front fender.  Is it the ABS? Has anyone heard a similar noise?

Front brake pads shifting slightly in the brembo caliper. Often heard on 08 and newer touring bikes.

 I have never heard of it escalating to the point where it causes a problem.

Is it only when the front brakes are applied? If so the noise could also be a sign of loose steering head bearings. The ABS should not make any noise unless it is activating.

yeah I have only heard it when from brake is applied, its a clanking sound.  I think it maybe the brake pad.

I've noticed it after backing and then the first application of the front brake. After that it's not there until I back up again.

yeah same here, I think that it can be attributed to that front brake

The "Clunk" is also at the 09SERG , it is caused by the swimming brake-rotors , the bolts are little smaller than the holes but that is a "must be" , you can check and hear it when  the frontwheel is lifted to turn free , take the rotors in both hands and try to push it forward and backwards , then you will hear the "Clunk" .

If it is the clunk when braking , then there is nothing to do , that`s normal .

I've noticed it also.  Wearing a full face helmet, I've tried to get it duplicate with the helmet off and I can never get it to duplicate. :nixweiss:

I'll try the backing up, then going forward.

This is a good thread, I beleive that this sound is normal due to the pad shifting.

not to the pad shifting but to the swimming brake-rotor .

perfectly normal with first application of front brake, nothing to worry about.
