I have exactly the same issue as the OP after replacing the original pads, disks and sensors with Pagid (which, as others have said, are also OEM).
I believe Doughboys suggestion is the correct one and that the squealing is caused by a build up of dust on the pads.
I actually removed the front pads/calipers and gave them another thoroughly good clean and this cured the problem for a while. Most of my driving is motorway, I got over 100k from the first set of pads/disks so I think dust build up on the pads is likely to be an ongoing problem. I did not have this problem with the Textar pads fitted originally - just a lot of difficult to shift black brake dust embedded in the alloys. This doesn't happen with the Pagids.
