Rear brake making "clunking" noise

Occasionally, when braking I hear a "clunking" noise from the rear break. Not only can I hear it, but I can feel it in the brake lever. I have inspected the brake several times and everything seems to be fine. Nothing is loose; all the bolts and pins are in place and tight. The brake pads have plenty of material on them, are positioned correctly and are not loose. The rotors are smooth and there are no hard spots that I can tell. The bike has 8000 miles on it. It doesn't happen every time I brake, just occasionally. But when it does happen, it's pretty loud. It does not seem to affect the braking, though, which is good.

Any thoughts as to what it might be? Anyone else ever experience this?

Cheers!

Are you sure the calliper is located on the swingarm properly ?

Often after having the rear wheel removed the front of the calliper is not located properly where it fits to the swingarm.

It sounds like the rear caliper bracket is not slotted into the swingarm correctly. Was the rear wheel ever removed at anytime prior? Alternatively you have may a damaged rotor.
Do you have a swingarm stand or center stand, to get the rear-end off the ground? Tie up your front brake (applied so it don't go anywhere), then run the bike in gear at idle speed (not cold start speed). Apply the rear brake slowly (gently) and watch for any movement / sound. Let us know what happens.

The clunk in my front wheel turned out to be a wheel bearing gone bad and cost me a wheel! Guess all the salt and other bad stuff they spray the roads with from Circle to Dead Horse got in the bearing.
If you take off and think its the disc a good surface plate for us poor guys is a pane of glass.Good for checking anything and cheap. Good luck.

I do have a center stand. I bought the bike new and although it has 8000 miles on it now, I have never had the wheel off the bike or changed the brake pads. The most I have ever done was adjust the chain tension. I have always made sure that the wheel was still aligned after each adjustment.

I have checked the disc rotor with a straight edge and it is absolutely flat as far as I can tell. No hard spots. The pads have at least half their material left.

It doesn't make the noise all the time. Just occasionally. I was thinking that it could be a loose caliper or maybe a loose pad, but all the bolts and pins are in the correct places. I have put marks on both the caliper and the pad to check if anything is moving but every time I check the marks, they are lined up.

I'll try putting it on the stand see if anything is moving. I was wondering if something was moving if I braked while reversing (I have to roll backwards to get it out of the garage).

Thanks for all the thoughts!

Cheers

Last time I had the caliper off the stainless clip that holds the pads toward the front of the bike fell out. Possibly that could make a noise.

Perhaps something else to check, is the play / sideways movement in your brake peddle. Maybe needs a bit of grease to move freely? Suggest that you consult an OEM parts listing site, for info on how the rear brake lever assembly is put together.

Hi, I recently have had the same exact problem. It usually happens the first time you touch the rear brake after it's been parked. By Buell did the same exact thing and recently my vstrom did have a rear tire change.
