Title: Rear brake noise (clunk)
Post by: Luke2718V on May 13, 2016, 08:13:17 PM
So my new SR has a rear brake assembly that doesn't sit exactly right. The channel that sits against the swing arm and keeps the assembly from rotating is wider than the round nubbin/bolt/bit/thingy that is welded to the inside of the swing arm. The result is that when I apply the rear brake, the assembly rotates a little and hits the thingy with an audible clunk. It doesn't happen 100% of the time, and I have figured out that if I never stop rolling forward it won't reset. However, once I come to full stop, or roll backward, it unsets and will clunk during the next brake application.

Has anyone else had this issue? Does it ever go away? How have you dealt with it (shims, ear plugs, ignoring it)?

Thanks

This has never happened with either of my bikes - there's a fair amount of friction holding the caliper retainers in place.

For now, you might try a heavy duty tie-wrap through the retainer & swingarm - I've seen this done to hold the brake in place during wheel removal.  At the next tire change, you could cut a small piece of thinwall clear tubing and hammer it onto the peg, maybe with a little heat and possibly some adhesive if you're sure it fits properly.

Electrical heat shrink tubing does the trick
