Caliper sliders look to be performing well, so it isn�t them. You�ve loosened the pinch bolts and compressed the forks a few times before retightening them. So all the usual stuff has been covered.

Just a thought, but is the front wheel (and/or spacers) fitted they right way round? It might not look it, but the front wheel is asymmetric about its centre line.

I�ve very nearly on a few occasions fitted a front tyre in the wrong direction because of this. I�ve now drawn arrows in marker pen on the disc carriers and a painted a red spot on the LH spacer so I don�t have the same trouble in the future.
