Hope someone can enlighten me. I recently fitted a jaybrake 6 piston brake caliper to my 07 Dyna street bob, front disc is the factory 11.5 inch full floating design type. Brake works great but recently started to hear a clunk in the front end when I applied them. After some investigation I found the outer section of the disc was moving on the floating rings that attach it to the inner section bolted to the hub. Has this happened to anyone else? Do I have to fit a solid type disc so this doesn't happen again? Any help appreciated.
