Disc knocking under breaking

I have recently fitted the Scootrs anti-dive upgrade and am getting a loud knocking at the end of the braking travel. I can't replicate it by pushing down whilst stationary so it's a bit difficult to see where it's coming from. It's only happened after adding the anti dive. I have adjusted the bracket slightly higher on the fork but this seems to only marginally improve it.

One of my BGM front shocks has lost it's click adjustment and I'm hoping this is just coincidence and not the damper bottoming out since the anti dive has been fitted?

Any ideas lads

Could be a bit of play in the linkage?
I replaced mine with a couple of rose joints.

I have the 2nd version with the rose joints. Mate has the old version and has same issues. I'm not sure if it's something hitting something or the noise from the the bracket itself making the noise?

Okay, fair to say this isn't a one off. Until we can work out what's causing the clunk it's going to be hard to fix it. My dampers need re furbing so they will off for a little while so if there's still clunking then they can be taken out of the equation.

are you using drum links? if so check the caliper bracket were it fits into the link , if there is any play it will knock under braking.
ah just seen you have only had problem since fitting anti dive, as said check for play in anti dive bar/brackets.

Check the nut on the underside of the top fastening, when I fitted my rose joint I heard a clunk under hard braking and it turned out to be that hitting the disc on the travel down !

Cheers andy, was it hitting the leading edge of the disc?
