Knocking sound from front caliper/calipers?

zx6r,they rattle around anyway the pads but today I heard a pronounced knocking sound,need to investigate I just wondered what it was? I dotn feel any pulsating when I brake with front lever so idk if its warped disc or discs?

I looked at the left side pad retaining pin and it wobbles about more than the right side so maybe its that?

discs arnt getting warm either so cant be rubbing much

Yh when I pull brake lever it stops,I'm hoping its worn loose pad pin,one definitely is loose compared to the other

Its really loud knock aswell

yh ive cleaned em today,its after you apply the brakes and they warm up the discs you can hear a clack clack sound then it goes

pads are really loose on these models though,i dotn think its serious just annoying,also found out one of the pistons had pushed half its dust seal out

yh and no,i think they improved the anti rattle on later models

I think they are different,they switched to radial calipers later,it could be a slightly warped disc idk,the tokico brakes are pretty rubbish tbh,nissin supposed to be much better

No the rivets are fine,its either one or more pistons arnt going back in enough or warped disc,but I can't feel it through the lever

had chance to look at it properly,spun wheel while it was off the ground,it does seem the retaining clip/tensioner isn't doing its job properly and the pad is flapping up and down as the disc spins

I do confess I bent the retaining bracket back to get the pads in because the bolt had seized in the caliper so couldn't take it off completely,i didn't think it would cause it to do that though,im gonna have to try and get the bolt out and bend the tensioner back
