Fork Chatter

I have a 2004 Ducati ST4s ABS, I love it Sargent seat raised and pulled bars back towards me K&N with Termi cans.
I have had issues with brake chatter coming and going seemed to get worse then better then worse again.


I have rebuilt the front forks fitted Ohlins springs and fork oil, stripped cleaned and rebuilt the calipers, refaced the pad material fitted the recommended banjo bolt to the master cylinder still had issues.


I noticed the brake rotors were not as loose as my 1098 some of the bobbins seemed too tight for me so I tried cleaning them with some success.


Took the front wheel off removed the rotors from the wheel attacked and removed the standard bobbins with my angle grinder fitted fully floating alloy bobbins seemed to be substantially lighter than the standard bobbins.


No more chatter works fine, disks move more easily than the originals on the carrier now.


Just what I found.
