Zitat von spainy im Beitrag #1 Sounds like something is really loose, and since the "clack" sound happens when you apply the brakes it may well be the rear brakes. I am assuming that the bike is in neutral when this rolling forward-backward demo in the video was done. Not sure what having the ignition in the "ON" position would do. If something was loose it would happen with the bike in the "OFF" position. However if applying only the handbrake (since both your feet were on the ground) then the "ON" position means that the linked brakes function was activated and the rear brake was being applied as well. Zitat von spainy im Beitrag #3 I think that there was a recent thread discussing floating brake discs. What you are showing in this video is normal and is likely not what is causing the "clack" in the first video. I suggest you put the bike on the centre stand and, while sitting on the ground, spin the rear wheel periodically apply the rear brake and see if you can better pinpoint the sound. If when the rear brake grabs there is that sound you should be able to localize the source. BTW - you can use the video icon (upper right of the text box) to include the video in your post. Makes it easier for the reader to click. video icon.png - Bild entfernt (keine Rechte) Regards, |

The disc moving seems to be excessive- does the other one move as much? My 35,000 mile discs don't have even half of that movement. Could be wear of the disc at the mounting holes or wear of the mounting hardware, or both. Also check for fore/aft movement of the brake pads in the calipers when brakes are applied.

Zitat von spainy im Beitrag #7The only way I see would be to take the wheel off and de-mount the discs to inspect. The locating bolts have a Loctite coating that you have to heat the bolts to remove. Once you have it apart, you can inspect the mounting holes and bolts/locators for wear. With that much movement, wear should be pretty evident. How many miles on your bike? It's also a good time to measure the disc thickness for wear. A riding mate has an RS with over 60,000 miles on and his discs are hardly any looser than mine at 35,000 mi. That tells me that the brake discs don't wear much in the rotating direction. Frank
