pinched brake line from fall?Stick to your keyboard. You suck at diagnosis. Lol!
Couple of things You can do to diagnose things. First take a small piece of scrap steel, approximately the same thickness as the rotor, remove the suspected caliper and slide the scrap steel between the pads in the same spot the rotor sits. Use a zip tie or some wire to hang the caliper in a way that the hoses aren't stressed, and pump the brake until the pads clamp the steel. If the symptom is gone, then the rotor is springing the pads back into the caliper bore.You too.
Another thing You can do requires a dial indicator. Clamp or bolt the indicator on the lower fork, and do a runout check on the rotor. Specs should be in the service manual.
