Caliper Knocking
Whats going on here
Its not the wheel bearing as iv had both calipers off and the wheel spins freely, no notches, right hand side caliper attached, spin wheel, its fine, add left hand caliper into the mix and this happens. Most annoying whilst riding around town.
I have replaced all seals and bleed the lines though i think one of the pistons is still sticking.. when i apply the brakes i have full braking power and no noises of judder. just when i release the brakes then this constant knocking noise seemingly every wheel rotation.

I don't think my rotor is warped, but then again i wouldn't know how to tell. I don't get any adverse feedback when my brakes are engaged, i get no pulsating feeling or noises when braking that are associated with warped rotors. Only when the brakes are released do i get this clunking noise

Hi bud when I had a similar noise on the same caliper on my bike (95 f3) my top pad spring was missing and it allowed the outer pad to tap on to the caliper body.
Also, when rotating the wheel look to see if the caliper body is moving inwards and outwards (that's a sure sign on a warped rotor). You could check the space between the rotor and the caliper body at the point when you get the tap noise to see if that's causing the problem too. How are the bobbins on the rotor too you should be able to turn them - a clean with some wd40 could help a little.
Hope you sort it bud
