Front brake or brakes making ch - ch - ch - ch - ch sound

[Welshy_Pete]

I took all the brakes of all apart. The pads are fine but I rough them up on the concreate. The calipers push in fine on both sides also slide fine. The discs had scratch lines on the passanger side you could feel with your nails. Then on the driver side it was starting to go there as well.

There nothing catching anywere at all checked both sides.

Ive put other discs on with other pads but still that noise.
