2009 Subaru (New pads, rotors, calipers) lots of brake dust on FD side Sign In

I finished replacing all 4 pads rotors and calipers on my 09 Impreza, and I've noticed (after 1k or so miles) a substantial amount of brake dust on my front driver's side wheel compared to all the rest. As said in subject all pads rotors and calipers are brand new (all good quality performance brand from rockauto). I made sure to bleed out the old brake fluid and replace with new. But I don't understand why this one side would create so much more dust than the others. Regardless of speed I hear no grinding or screeching. The car also does not pull to one side while hitting the brakes (even while hitting brakes hard). I can't imagine why this is happening, because I have never had this problem in the past.

The slides could be binding, the flex hose could be ruptured internally or the caliper could be sticking.

Same as what Hammer just said. Add that one showing dust not others is dragging for those reasons. I think you may feel the heat at that wheel vs others know it's dragging then it's WHY?
You did it, was parking brake working properly and releasing fully? Some or many Subarus use fronts for parking brake should be built into caliper - I don't do many Subaru things by chance can't know them all by year.
Most would compensate for the left/right pull you'd expect as they have ALL wheels involved and always have,
