Sound at front end under braking/deceleration

[darrsi]

I got the front wheel off the floor and spun it several times.


I get a faint clicking or clacking (clacking is a better description) noise and it comes from the offside front caliper.


And here's the interesting bit:  It seems to be once every wheel rotation.


And it seems to be when the same point of the disc passes through the pads.


So I checked the offside front disc, and found........ absolutely nothing...... at least not yet.

It can be caused by cheaper, ill fitting pads, grooves in the pad pin stopping the pads from sliding back properly, or even a worn caliper housing.
Start simple and give the pad pins a good clean up, and make sure there aren't any grooves formed from rocking back and forth, then give them a light copper grease and see if it improves at all?
