Caliper knocking

[Tank.]

so I changed the brakes all round a few months ago.

Now I'm getting a hollow knocking noise occasionally when braking and without fail braking after changing direction i.e manoeuvring

After speaking to a few folk and my boss listening to the sound and symptoms folk reckon it's the caliper moving. Ive taken both front wheels off and caliper bolts are tight, has anyone else experienced this and know the solution?

All help greatly appreciated

Have you replaced the retaining spring properly (number 4)?

Replaced with brand new retaining springs and I believe i fitted them correctly
