I was thinking maybe the discs are off and they are pushing pistons so I have grind the discs and indeed they ware off center and now the gap is 0.15 after a while but on all 4 pads. Strange. I also did not use handbrake this time.Odd that you should reply today. LOL. I just adjusted mine again today. Inners were fine. couldn't get a .001" feeler gauge between rotor and pad on those. Outers were loose, but nothing like what you're experiencing. .
Maybe the surface on pads and pistons must be very smooth for proper piston self adjustment. If the pistons do little movement around their axis when they self adjust and the surface is not smooth, maybe that can affect. :001_unsure:
