Clunk noise when using rear brake

[leenaqvi]

Yes the arm was moved to down position as in the picture in the my first post. However to move it to the down position it was removed from the brake housing and them rotated to the down position. The clunk has really only happened when I was testing the rear brake, so I was braking hard at a fairly low speed. The link below talks about this kind of clunk being common from hard braking on rear wheel. I don't normally use only the rear brake. I was just testing it after the tires were changed and since it made a clunk I was testing again with hard rear braking to see if the clunk would come back.

Little to none of this link has much to do with your situation. Just put your bike back together the way it is supposed to be. Then you can be sure nothing odd is in the mix. Make sure there is a small spring attached to the ends of the brake shoes to keep them pulled up against the cam when the brakes are not being used. This keeps them in their proper position and ready to use. I have a feeling the spring has gone AWOL during the rear wheel removal. Take pics of your procedure so we can see first hand what is going on. We can help you with the job and talk you through anything you don't understand. Most of us have been there done that in our riding careers. We learn through experience and great folks willing to share their knowledge. There are no dumb questions, if you are unsure of something, no matter how trivial, we can help.

By the way, please learn to use both brakes to their maximum. Practice emergency braking so you know what to expect when things get dicey.

Maybe you need a new lock washer or it is missing at the torque link.
I had a symptom of clunking that was alccompanied with brake "grab"
Just had to replace the lock washer because the old one was compressed flat.

Had the exact same clunking issue. That lock washer was missing on my bike. Apparently the last person that did a rear brake job on it lost the washer and just didn't think it was important enough to replace.

Put one on and immediately the clunking stopped.
