I doubt very much the dust shield removed does anything as the caliper is a floating type and basically self centers over rotor. We're talking a fraction of a mm here. Lots of people, including myself, have removed them without any issues.

You seem to be on the right track for the MC and booster issues. Try disconnecting the brake pedal to booster rod and see if it moves further back than the pedal. I am willing to bet that it's the piston pusher pill in the booster to MC that's the problem. I remember faintly that someone had the same issue and it was this pill that was too long.

I've heard of that, and I basically did the same thing by adding a couple washers between the booster and master cylinder, but that is all a bandaid for whatever the real issue is, and if it's the lack of shields at the wheels, then I just need to get those and put them back on.
